I/O
Option
Description
PA0~PA7
I/O
Wake-up,
Pull-high
or None
Bidirectional 8-bit I/O port. Each pin can be configured as a wake-up input by
configuration option. Software instructions determine the CMOS output or
Schmitt trigger input with or without pull-high resistor (configuration option).
PB0~PB3
I/O
Pull-high
or None
Bidirectional 4-bit I/O port. Software instructions determine the CMOS output or
Schmitt trigger input (pull-high resistor depending on configuration option).
VSS
Negative power supply, ground
VDD
Positive power supply
VSSP
PWM negative power supply, ground
VDDP
PWM positive power supply
RES
I
Schmitt trigger reset input, active low
OSC1,
OSC2
RC or
Crystal
OSC1 and OSC2 are connected to an RC network or crystal (by configuration
option) for the internal system clock. In the case of RC operation, OSC2 is the
output terminal for 1/4 system clock. The system clock may came form the crys-
tal, the two pins cannot be floating.
PWM1,
PWM2
O
PWM output for driving a external transistor or speaker.
