PA0~PA7
I/O
Pull-high*
Wake-up
CMOS/schmitt
trigger input
Bidirectional 8-bit input/output port. Each bit can be
configured as a wake-up input by mask option. Soft-
ware instructions determine the CMOS output or
schmitt trigger or CMOS input with pull-high resistor
(determined by pull-high options).

I/O
Pull-high*
I/O or BZ/BZ
CMOS/schmitt
trigger input
Bidirectional 8-bit input/output port. Software in-
structions determine the CMOS output or schmitt
trigger input with pull-high resistor (determined by
pull-high options).
The PB0 and PB1 are pin-shared with the BZ and BZ,
respectively. Once the PB0 and PB1 are selected as
buzzer driving outputs, the output signals come from
an internal PFD generator (shared with timer/event
counter 0).
21~24,

PD0~PD7
I/O
Pull-high*
CMOS/schmitt
trigger input
Bidirectional I/O lines. Software instructions deter-
mine the CMOS output or schmitt trigger input with
pull-high resistor (determined by pull-high options).

VSS
Negative power supply, ground
11
PG0/INT
I/O
Pull-high*
Bidirectional I/O lines. Software instructions deter-
mine the CMOS output or schmitt trigger input with
pull-high resistor (determined by pull-high options).
This external interrupt input is pin-shared with PG0.
The external interrupt input is activated on a high to
low transition.

Timer/event counter 0 schmitt trigger input (without
pull-high resistor)

I/O
Pull-high*
CMOS/schmitt
trigger input
Bidirectional I/O lines. Software instructions deter-
mine the CMOS output or schmitt trigger input with
pull-high resistor (determined by pull-high options).

Timer/event counter 1 schmitt trigger input (without
pull-high resistor)
