Each pin can be configured as a wake-up input by a configuration option. Software instructions determine if the pin is a CMOS output or input. Configuration options determine if the pins have pull-high resistors. Configuration options determine whether the CMOS or NMOS pins are configured as CMOS or NMOS pins. Configuration options deterSchmitt trigger or mine whether the pins are configured with Schmitt trigger or non-Schmitt non-Schmitt trigger inputs. PA2 is shared with the external timer input pin TMR0. PA3 is trigger shared with the external timer input pin TMR1. PA0 and PA1 are shared with the Z1 and Z2 pins. PA4~ PA7 are pins shared with SPI interface. Bidirectional 8-bit input/output port. Each pin, PB0 and PB1 can be configured as wake-up inputs using configuration options. Two configuration options, one for pins PB2 and PB3 and one for pins PB4~PB7, can also setup these pin groups as wake-up inputs. Software instructions determine if the pin is a CMOS output or Schmitt Trigger input. Configuration options determine if each nibble, PB0~PB3 and PB4~PB7 have pull-high resistors. PB0 and PB1 are shared with the V1 and V2 pins. Bidirectional 8-bit input/output port. Each nibble, PC0~PC3 and PC4~PC7, can be configured as wake-up inputs by configuration options. Software instructions determine if the pin is a CMOS output or Schmitt.
