* put the actual drive controller electronics onto the drive
* itself, and have the host machine just talk to that using
* a simpe, standardized I/O path- hence the name IDE, for
* Integrated Drive Electronics.
*
* In the ATA version of IDE, the programming interface of
* the IBM PC/AT (which used the Western Digitial 1002/1003
* controllers) was kept, and, so, ATA-IDE assumes a 16bit
* data path: it reads and writes 16bit words of data. The
* disk drives for this bus commonly have an 'A' suffix to
* identify them as 'ATBUS'.

* out on the SQW pin. When the SQWE bit is set to 0, the
* SQW pin is held low. SQWE is a read/write bit and is
* cleared by !RESET. SQWE is low if disabled, and is high
* impedance when VCC is below VPF. SQWE is cleared to 0 on
* !RESET.
* * Square-Wave Enable (SQWE)
* When this bit is set to 1, a square-wave signal at the
* frequency set by the rate-selection bits RS3-RS0 is driven
* out on the SQW pin. When the SQWE bit is set to 0, the
* SQW pin is held low. SQWE is a read/write bit and is
* cleared by !RESET. SQWE is low if disabled, and is high
* impedance when VCC is below VPF. SQWE is cleared to 0 on
* !RESET.
*
* * Update-Ended Interrupt Enable (UIE)
* This bit is a read/write bit that enables the update-end
* flag (UF) bit in Register C to assert !IRQ. The !RESET
* pin going low or the SET bit going high clears the UIE bit.
* The internal functions of the device do not affect the UIE
* bit, but is cleared to 0 on !RESET.
* * Update-Ended Interrupt Enable (UIE)
* This bit is a read/write bit that enables the update-end
* flag (UF) bit in Register C to assert !IRQ. The !RESET
* pin going low or the SET bit going high clears the UIE bit.
* The internal functions of the device do not affect the UIE
* bit, but is cleared to 0 on !RESET.
*
* * Alarm Interrupt Enable (AIE)
* This bit is a read/write bit that, when set to 1, permits
* the alarm flag (AF) bit in Register C to assert !IRQ. An
* alarm interrupt occurs for each second that the three time
* bytes equal the three alarm bytes, including a don't-care
* alarm code of binary 11XXXXXX. The AF bit does not
* initiate the !IRQ signal when the AIE bit is set to 0.
* The internal functions of the device do not affect the AIE
* bit, but is cleared to 0 on !RESET.
* * Alarm Interrupt Enable (AIE)
* This bit is a read/write bit that, when set to 1, permits
* the alarm flag (AF) bit in Register C to assert !IRQ. An
* alarm interrupt occurs for each second that the three time

* initiate the !IRQ signal when the AIE bit is set to 0.
* The internal functions of the device do not affect the AIE
* bit, but is cleared to 0 on !RESET.
*
* * Periodic Interrupt Enable (PIE)
* The PIE bit is a read/write bit that allows the periodic
* interrupt flag (PF) bit in Register C to drive the !IRQ pin
* low. When the PIE bit is set to 1, periodic interrupts are
* generated by driving the !IRQ pin low at a rate specified
* by the RS3-RS0 bits of Register A. A 0 in the PIE bit
* blocks the !IRQ output from being driven by a periodic
* interrupt, but the PF bit is still set at the periodic
* rate. PIE is not modified b any internal device functions,
* but is cleared to 0 on !RESET.
* * Periodic Interrupt Enable (PIE)
* The PIE bit is a read/write bit that allows the periodic
* interrupt flag (PF) bit in Register C to drive the !IRQ pin
* low. When the PIE bit is set to 1, periodic interrupts are
* generated by driving the !IRQ pin low at a rate specified
* by the RS3-RS0 bits of Register A. A 0 in the PIE bit
* blocks the !IRQ output from being driven by a periodic
* interrupt, but the PF bit is still set at the periodic
* rate. PIE is not modified b any internal device functions,
* but is cleared to 0 on !RESET.
*
* * SET
* When the SET bit is 0, the update transfer functions
* normally by advancing the counts once per second. When
* the SET bit is written to 1, any update transfer is
* inhibited, and the program can initialize the time and
* calendar bytes without an update occurring in the midst of
* initializing. Read cycles can be executed in a similar
* manner. SET is a read/write bit and is not affected by
* !RESET or internal functions of the device.
* * SET
* When the SET bit is 0, the update transfer functions

* the SET bit is written to 1, any update transfer is
* inhibited, and the program can initialize the time and
* calendar bytes without an update occurring in the midst of
* initializing. Read cycles can be executed in a similar
* manner. SET is a read/write bit and is not affected by
* !RESET or internal functions of the device.
*
* * Update-Ended Interrupt Flag (UF)
* This bit is set after each update cycle. When the UIE
* bit is set to 1, the 1 in UF causes the IRQF bit to be
* a 1, which asserts the !IRQ pin. This bit can be
* cleared by reading Register C or with a !RESET.
* * Update-Ended Interrupt Flag (UF)
* This bit is set after each update cycle. When the UIE
* bit is set to 1, the 1 in UF causes the IRQF bit to be
* a 1, which asserts the !IRQ pin. This bit can be
* cleared by reading Register C or with a !RESET.
*
* * Alarm Interrupt Flag (AF)
* A 1 in the AF bit indicates that the current time has
* matched the alarm time. If the AIE bit is also 1, the
* !IRQ pin goes low and a 1 appears in the IRQF bit. This
* bit can be cleared by reading Register C or with a
* !RESET.
* * Alarm Interrupt Flag (AF)
* A 1 in the AF bit indicates that the current time has
* matched the alarm time. If the AIE bit is also 1, the
* !IRQ pin goes low and a 1 appears in the IRQF bit. This
* bit can be cleared by reading Register C or with a
* !RESET.
*
* * Periodic Interrupt Flag (PF)
* This bit is read-only and is set to 1 when an edge is
* detected on the selected tap of the divider chain. The
* RS3 through RS0 bits establish the periodic rate. PF is
* set to 1 independent of the state of the PIE bit. When
* both PF and PIE are 1s, the !IRQ signal is active and
* sets the IRQF bit. This bit can be cleared by reading
* Register C or with a !RESET.

*
* * Interrupt Request Flag (IRQF)
* The interrupt request flag (IRQF) is set to a 1 when one
* or more of the following are true:
* - PF == PIE == 1
* - AF == AIE == 1
* - UF == UIE == 1
* Any time the IRQF bit is a 1, the !IRQ pin is driven low.
* All flag bits are cleared after Register C is read by the
* program or when the !RESET pin is low.
* * Interrupt Request Flag (IRQF)
* The interrupt request flag (IRQF) is set to a 1 when one
* or more of the following are true:
* - PF == PIE == 1
* - AF == AIE == 1
* - UF == UIE == 1
* Any time the IRQF bit is a 1, the !IRQ pin is driven low.
* All flag bits are cleared after Register C is read by the
* program or when the !RESET pin is low.
*
* * Valid RAM and Time (VRT)
* This bit indicates the condition of the battery connected
* to the VBAT pin. This bit is not writeable and should
* always be 1 when read. If a 0 is ever present, an
* exhausted internal lithium energy source is indicated and
* both the contents of the RTC data and RAM data are
* questionable. This bit is unaffected by !RESET.
