Advanced Technology Attachment Controller (ATA)
23.5.2
This section contains the detailed register descriptions for the ATA registers.
23.5.2.1
The ATA interface works both in little endian or big endian mode. The addresses of all registers are
independent of endianess mode. (they remain same.) The few 16-bit and 32-bit registers represent strings
of 2 or 4 bytes. The byte order in the 16-bit or 32-bit register is dependent on endianess selection.
