Pin Description
Pin Name I/O Code Option Pull-high Wake-up Description Bidirectional 8-bit input/output port. Each bit can be configured as wake-up input 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.
