Description
PD0/PWM
I/O
Pull-high
I/O or PWM
Bidirectional 1-bit input/output port. Software instructions deter-
mine the CMOS output, Schmitt trigger input with or without a
pull-high resistor (determined by pull-high option: port option).
The PWM output function is pin-shared with PD0 (dependent on
PWM optios).
RES
I
Schmitt trigger reset input. Active low.
VDD
Positive power supply
OSC1
OSC2
I
O
Crystal or RC
OSC1, OSC2 are connected to an RC network or a Crystal (de-
termined by options) for the internal system clock. In the case of
RC operation, OSC2 is the output terminal for 1/4 system clock.
