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.
• V_SS (Input)
Ground.
• V_DD (Input)
Supply Voltage.
