Peripheral Control Signals
•
POR (Input, Schmitt-Triggered, 100K Pull-Up)
Local Power-On Reset signal. A 0.1mF capacitor is recommended on
this pin to GND to generate a POR.
•
•
M_PINT (Output, Tri-State, 8 mA)
Interrupt to local microprocessor
PC_MCLK_IN (Input, Schmitt-Triggered)
Master Clock In. This is an input signal. This clock signal is used to
generate all internal timing. All local bus signals are asynchronous to
this clock.

•
•
EXTP_STSCHG/RES2 (Input, 100K Pull-Up)
Status Change Input. This signal outputs the value of the status
changed line on the PCMCIA bus if enabled in the CCR register, or it
is an input for bit 7 (RSVDEVT3) in CCR4.
EXTP_AUDIO (Input 100K Pull-Up)
Audio Input. This input signal reflects the audio output. This signal is
active High, and the Speaker output on the PCMCIA bus is active
Low.
EXTP_PWDN (Output, 8 mA)
Power Down Output. This signal reflects the state of the Power Down
bit in the CCR.
