PCMCIA Interrupt Request (Output, active Low): After the PCMCIA inter-
face is reset it is in a MEMORY-ONLY mode, and this signal is driven Low
to signify a Busy state until the 380C writes a register bit to indicate it is
ready. After the card is then configured by the Host, PCIRQ goes Low to re-
quest a Host PC interrupt when the internal INT0 signal is asserted by the
MIMIC. PCIRQ is monitored by the PCMCIA Host adapter and, dependent
on the configuration, connected to one of the Host interrupts (for example,
COM1 or COM2 interrupt). PCIRQ can be programmed to be a pulsed inter-
rupt with a minimal pulse length of one microsecond, or a level-interrupt that
is reset when the interrupt is processed by the Host. This choice is made by
means of bit 6 of the Configuration Option Register.

PCMCIA Reset (input, active High): Setting PCRESET High resets the PC-
MCIA interface. The card configuration register is cleared and the PCMCIA
interface operates in the MEMORY-ONLY mode until it is configured again.
The attribute memory has to be initialized by the controller, and the Ready/
Busy (PCIRQ) signal has to be deactivated.

PCMCIA Status Change (output): This output is controlled by a bit in the
PCMCIA module’s 380C Control Register.
