During normal operations this pin is used to select the IDE controller.
CS1 decodes the HDC addresses 3F6H and 3F7H (376H, 377H).
During power-on reset this pin selects the HDC address and is pulled
up internally.
When set to high, it selects I/O port address range 1F0H-1F7H
(3F6H-3F7H) (default).
When set to low, it selects I/O port address ranges 376H-377H and
170H-177H.
CS1 can be programmed by CR0D register as output pin IRTX3 for
serial infrared communication.
During normal operation this pin is used to select the IDE controller.
CS0 decodes HDC addresses 1F0H-1F7H (170H-177H).
During power-on reset this pin is pulled down internally and used to
enable or disable the IDE.
When it is set to high, IDE is disabled.
When it is set low, IDE is enabled (default).

Direction of the head step motor. An open drain output.
Logic 1 = outward motion
Logic 0 = inward motion
Head select. This open drain output determines which disk drive
head is active.
Logic 1 = side 0
Logic 0 = side 1
Reduced write current. This signal can be used on two-speed disk
drives to select the transfer rate. An open drain output.
Logic 0 = 250Kbps
Logic 1 = 500Kbps
When bit 5 of CR9 (EN3MODE) is set to high, the three-mode FDD
function is enabled, and the pin will have a different definition. Refer
to the EN3MODE bit in CR9.
Write data. This logic low open drain writes precompensation serial
data to the selected FDD. An open drain output.
