System Memory Write
An active-low memory write signal
This pin drives data output to a PC card pointed to by a system address.
System Memory Read
An active-low memory read signal
This pin drives data input from a PC card pointed to by a system address.
16-bit Memory Select
An active high signal, indicating to the host system that the PC card
is in the 16-bit memory access mode.
System Address Enable
System Bus High Enable
An active-low signal, indicating the high byte of the 16-bit system
data bus
Register Base Address Select
This pin selects the base address of a register. This pin is driven
by a system reset signal (RSTD) and determines the address decode
value of a register according to this input when PCICs are connected
in a cascade fashion. While resetting is not executed, this pin works
as a speaker-out output. (This pin is a bi-directional pin.)
The digital audio signal from the card is output through this pin.
No-Wait State
An active-low signal, indicates that the PC card executes no-wait
accessing
This pin is disabled during a 16-bit I/O cycle, and in the other cycle,
is enabled by register setting.
Interrupt Request
An active-high signal, outputting an interrupt request to the host
system. Each slot assigns one of the IRQ pins as an interrupt signal.
I/O Channel Interrupt
An active-low signal, outputting a non-maskable interrupt request
(NMI) to the CPU (maskable by system hardware configuration)
Card Detect
An active-low signal detecting proper card insertion.
The status of this pin is reflected on the contents of registers.
The status transition of this pin can be used as an interrupt request
by register setting.
