MISC0 - Miscellaneous Control Register 0 - (write 2Eh)
Bit 7: HIIEN - Host Interface Interrupt Enable
Setting this bit high enables the microprocessor interrupt of the host interface. Host interface
interrupt occurs at the following conditions:
SRST (Device Control Register) is written as 1 after 0 to either master or slave drive.
Execute Drive Diagnostics Command is written to either master or slave drive.
Any opcode is written to the ATAPI Command Register while the drive is selected except:
(1) command opcode is 08h, (2) command opcode is A0h and APKTEN (18h.7) is high.
IDE interface interrupt is cleared by the following:
Chip reset or host reset
Reading register 37h
Writing 1 to CLRBSY (20h.4)
Bit 6: Reserved
Bit 5: DRVEb - Drive Selection Enable
Setting this bit low enables selection of the drive if bit DRV in ATAPI Drive Select Register
matches the setting of MDRV (2Eh.4).
Bit 4: MDRV - Master Drive
Setting this bit high sets the drive to be selected when bit DRV in the ATAPI Drive Select Register
is set to 0 (Master Drive).
