IDE Command Block Register
This register is a Command Block Register that is the I/O port of the IDE interface.
The transfer mode of the Data Register is PIO mode-fixed, having access based on conditions set on the IDE_PioDmaCyc
Register. Since the setting at the BUS8/SWAP bit of the CONFIG Register is reflected, 16-bit access is possible by always
accessing the Data Register twice if it is 16 bits wide.
During DMA transfer, access to the Data Register is disabled.
If you access the 0x71-0x77 in the DMA mode or when the InterLock bit is not on, the HDMARQ is negated once and CPU
access is done.
When the Interlock bit is on or at the time of UltraDMA, the XHDMACK is negated at the time of HDMAQR off or on
completion of transfer. Note that, for this reason, the CPU access is put in wait state.
