LPC TO ISA BRIDGE SET
W83626F/W83626D
CR04 (GPIO Status Register , Default 0ss00sssb)
PRELIMINARY
If the GPIO is selected GPIO function, it will be controlled by CR10,13,14,15,and 16.The pins were
set non-GPIO functions by power-on setting pin or software programmed.
Bit 7(GPIO7) : = 1 Signal used as IOHCS# (Set by software only)
= 0 Signal used as GPIO function (Default)
Bit 6 (GPIO6): = 1 Signal used as RTCCS# (Set by pin123 RTCEN# )
= 0 Signal used as GPIO function (Default)
Bit 5 (GPIO5): = 1 Signal used as IRQ8 (Set by Pin 123 RTCEN# )
= 0 Signal used as GPIO function (Default)
Bit 4 (GPIO4): = 1 Signal used as PLED ( Set by software only and programmed by CR CR17 bit [5,4])
= 0 Signal used as GPIO function . (Default)
Bit 3 (GPIO3): = 1 Signal used as IRQIN (depended on CR17 bit[3..0])
= 0 Signal used as GPIO function (Default)
Bit 2 (GPIO2): = 1 Signal used as MCCS# (decode address 62h and 66h )
by Pin 36 KBEN# power-on setting
= 0 Signal used as GPIO function (Default)
Bit 1 (GPIO1): = 1 Signal used as KBCS# (decode address 60h and 64h)
by Pin 36 KBEN# power-on setting
= 0 Signal used as GPIO (Default)
Bit 0 (GPIO0): = 1 Signal used as IRQ1 by Pin 36 KBEN# power-on setting
= 0 Signal used as GPIO (Default)
CR05 (System Clock Register , Default 0x4D)
