5 / 98 page PinDescription PinName I/O Options Description PA0/SCSA PA1/SCLKA PA2/SDIA PA3/SDOA PA4/PWM0 PA5/PWM1 PA6/INT PA7/TMR0 I/O Pull-high Wake-up NMOS or CMOS Bidirectional 8-bit input/output port. 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 Schmitt Trigger input. Configuration options determine if the pins have pull-high resistors. The INTB and TMR0 pins are pin-shared with PA6 and PA7 respectively. PA0~PA3 are shared with the SPIA function.PA4~PA5aresharedwithPWM0andPWM1. PB0/AN0/SCSB PB1/AN1/SCLKB PB2/AN2/SDIB PB3/AN3/SDOB PB4/AN4 PB5/AN5 PB6/AN6 PB7/AN7/VDDIO I/O Pull-high Wake-up PB7/VDDIO PB0~PB6 with VDDIO Bidirectional 8-bit input/output port. Each nibble, PB0~PB3 and PB4~PB7 pin can be configured as a wake-up input by a configuration option. Soft- ware instructions determine if the pin is a CMOS output or Schmitt Trigger input. Configuration options determine if the pins have pull-high resistors. PB is pin shared with the A/D inputs. Once a PB line is selected as an A/D input using software control, the I/O function and pull-high resistor are dis- abled automatically. PB7 can be configured as a normal I/O or a VDDIO pin by configuration option. The power supply for pins PB0~PB6 can be set to either VDD or VDDIO by configuration options. PB0~PB3 are shared with SPIB. PC0/AN8~ PC7/AN15 I/O Pull-high Wake-up Bidirectional 8-bit input/output port. Each nibble, PC0~PC3 and PC4~PC7 pin can be configured as a wake-up input by a configuration option. Soft- ware instructions determine if the pin is a CMOS output or Schmitt Trigger input. Configuration options determine if the pins have pull-high resistors. PC is pin shared with the A/D inputs. Once a PC line is selected as an A/D input using software control, the I/O function and pull-high resistor are dis- abledautomatically. PD0/TMR1 PD1~PD7 I/O Pull-high Wake-up Bi-directional 8-bit input/output port. Each nibble, PD0~PD3 and PD4~PD7 pin can be configured as a wake-up input by a configuration option. Soft- ware instructions determine if the pin is a CMOS output or Schmitt Trigger input. Configuration options determine if the pins have pull-high resistors. TheTMR1pinissharedwithPD0.
