Table 40:
In 8-bit bus mode, the 16-bit Task File register 1F0 requires 2 consecutive write/read
accesses before the proper PIO write/read is generated on the IDE interface. The first
byte is always the lower byte (LSByte). Other task file registers can be accessed
directly.
Writing to Task File registers can be done in any order except for Task File register
1F7, which must be written last.
