Bidirectional 8-bit input/output port. Each pin can be configured as a
wake-up input by options. Software instructions determine the CMOS output
or Schmitt trigger input with pull-high resistor (determined by pull-high options).
Bidirectional 8-bit input/output port. Software instructions 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 BZ and BZ, respectively. Once the
PB0 or PB1 is selected as buzzer driving outputs, the output signals come
from an internal PFD generator (shared with timer/event counter).
Negative power supply, ground
Bidirectional I/O lines. Software instructions determine the CMOS output or
Schmitt trigger input with pull-high resistor (determined by 1-bit pull-high op-
tions). The external interrupt and timer input are pin-shared with PC0 and
PC1, respectively. The external interrupt input is activated on a high to low
transition.
Schmitt trigger reset input. Active low.
Positive power supply
OSC1and OSC2 are connected to an RC network or Crystal (determined by
options) for the internal system clock. In the case of RC operation, OSC2 is
the output terminal for 1/4 system clock.
