pulled-up internally. The pin applied a pull-down resistor (4.7K
ohm) to enable K/B functions. (IRQ1,KBCS#,and MCCS#)
ROMCS#, this pin enable positive decoder of BIOS address range
[depend on CR03, bit 1 or external weak pulled-up during PCIRST
is asserted].
General purpose I/O pin 0.
Parallel Interrupt Requested Input 1. This interrupt request is used
for specific K/B functions.
General purpose I/O pin 1.
Decode the address 60h and 64h to output chip selected signal.
Enable by KBEN# power-on setting.
General purpose I/O pin 2.
Decode the address 62h and 66h to output chip selected signal
Enable by KBEN# power-on setting
General purpose I/O pin 3.
Programmable parallel IRQ input transfers to serial IRQ
Enable by KBEN# power-on setting
General purpose I/O pin 4.
Power LED output, this signal is low after system reset.
General purpose I/O pin 5.
Parallel Interrupt Requested Input 8. This interrupt request is used
for specific RTC functions. Enable by RTCEN# power-on setting
General purpose I/O pin 6.
Decode the address 70h and 71h to output chip selected signal
Enable by RTCEN# power-on setting
General purpose I/O pin 7.
Decode SA [15-11] is all 0 and setting by CR04 Bit 6.
K/B Functions Enable. During power-on reset this pin is weak
