ISA address bus bit 0-3.
When in LPC mode, these pins become LPC to ISA address
output.
CPU I/O read signal.
When in LPC mode, these pin becomes LPC to ISA IOR output.
CPU I/O write signal.
When in LPC mode, these pin becomes LPC to ISA IOW output.
ISA address bus bits 7-10.
When in LPC mode, these signal lines communicate address,
control, and data information over the LPC bus between a host
and a peripheral.
ISA address bus bit 6
In LPC mode, this pin acts as PCI clock input.
ISA address bus bit 5
In LPC mode, indicates start of a new cycle or termination of a
broken cycle.
ISA address bus bit 4.
In LPC mode, Serial IRQ input/Output.
ISA data bus bits 0-7
When in LPC mode, the pins become LPC to ISA data bus bits
0-7.
System clock input. According to the input frequency 24MHz or
48MHz, it is selectable through register. Default is 24MHz
input.
Default is ISA IRQ output, can act as GPIO function by
programming register. About IRQ index setting please refer to
pin67.
When in LPC mode, this pin acts as GPIO function
Default is ISA IRQ output, can be GPIO by programming
register. About IRQ index setting please refer to pin33.
When in LPC mode, this pin acts as GPIO function
