Each pin can be configured as wake-up input by configuration options. Software instructions determine if the pin is a CMOS output or Schmitt trigger input. Configuration options determine which pins on the port have pull-high resistors. The PFD, TMR and INT pins are pin-shared with PA3, PA4 and PA5, respectively. Bidirectional 8-bit input/output port. Software instructions determine if the pin is a CMOS output or Schmitt trigger input. Configuration options determine which pins on the port have pull-high resistors. Pins PB0~PB3 are pin-shared with the A/D input pins. The A/D inputs are selected via software instructions. Once selected as an A/D input, the I/O function and pull-high resistor are disabled automatically. Bidirectional 8-bit input/output port. Software instructions determine if the pin is a CMOS output or Schmitt trigg.
