I/O
Pull-high
Wake-up
PA3 or PFD
Bidirectional 8-bit input/output port. Each bit can be
configured as wake-up input by ROM code option.
Software instructions determine the CMOS output or
Schmitt trigger input with or without pull-high resistor
(determined by pull-high options: bit option). The PFD,
TMR and INT are pin-shared with PA3, PA4 and PA5,
respectively.

PB3/AN3
I/O
Pull-high
Bidirectional 4-bit input/output port. Software in-
structions determine the CMOS output, Schmitt trig-
ger input with or without pull-high resistor
(determined by pull-high options: bit option) or A/D in-
put.
Once a PB line is selected as an A/D input (by using
software control), the I/O function and pull-high
resistor are disabled automatically.

VSS
Negative power supply, ground.

PD0/PWM
I/O
Pull-high
PD0 or
PWM
Bidirectional I/O line. Software instructions deter-
mine the CMOS output, Schmitt trigger input with or
without a pull-high resistor (determined by pull-high
options: bit option). The PWM output function is
pin-shared with PD0 (dependent on PWM options).

RES
I
Schmitt trigger reset input. Active low.

OSC1
OSC2
I
O
Crystal
or RC
OSC1, OSC2 are connected to an RC network or a
Crystal (determined by ROM code option) for the in-
ternal system clock. In the case of RC operation, OSC2
is the output terminal for 1/4 system clock.
