Description
Bidirectional 8-bit input/output port. Each bit can be configured as wake-up in-
put by options. Software instructions determine the CMOS output or Schmitt
trigger input with a pull-high resistor (determined by pull-high options).
Bidirectional 3-bit input/output port. Software instructions determine the
CMOS output or Schmitt trigger input with a pull-high resistor (determined by
pull-high options).
Positive power supply
Negative power supply, ground
OSC1, OSC2 are connected to an RC network or a crystal (determined by
code option) for the internal system clock. In the case of RC operation, OSC2
is the output terminal for 1/4 system clock (NMOS open drain output).
Schmitt trigger reset input. Active low.
