Each bit can be configured as a wake-up input by configuration option. Software instructions determine if the pin is a CMOS output or Schmitt trigger input with or without pull-high resistor (determined by pull-high option: bit option). Pins PA0, PA1 and PA3 are pin-shared with BZ, BZ and PFD, respectively. Bidirectional 4-bit input/output port. Software instructions determine if the pin is a CMOS output or Schmitt trigger input with or without pull-high resistor (determined by pull-high option: bit option). Bidirectional 1-bit input/output port. Software instructions determine if the pin is a CMOS output or Schmitt trigger input with or without pull-high resistor (determined by pull-high option: bit option). RMT with wake-up function (both rising and falling edge) and Schmitt trigger input with or without a pull-high resistor (determined by pull-high option). Note: The RMT is pin-shared with PC7. When this pin is used as an RMT input, the pin should be setup as an input, to prevent the I/O pin influencing the operation of the RMT.
