After detecting the interrupt, the host reads the ATAPI Status Register and if necessary, the Error
Register for the command completion status.
ASCTRL - Automatic Sequence Control register - (read/write 18h)
Bit 7: APKTEN - Automatic Packet Transfer Enable
Setting this bit high enables Automatic Packet Transfer logic. When APKTEN is high, the
following hardware sequence is performed if host issues opcode A0h to the ATA Command
Register if drive has been selected:
Set BSY (37h.7)
APKT (30h.0)
