Bidirectional 8-bit input/output port. Each bit can be configured as a
wake-up input by ROM code option. The input or output mode is con-
trolled by PAC (PA control register).
Pull-high resistor options: PA0~PA7
CMOS/NMOS/PMOS options: PA0~PA7
Wake up options: PA0~PA7
PA6 and PA7 are pin-shared with TMR0 and TMR1 input, respectively.
Bidirectional 8-bit input/output port. Software instructions determine the
CMOS output or Schmitt trigger input with pull-high resistor (determined
by pull-high options).
Wake-up options: PB0~PB5
Falling edge wake-up options: PB6, PB7
PB6 is wire-bonded with SCL pad of the Data EEPROM
PB7 is wire-bonded with SDA pad of the Data EEPROM
Bidirectional I/O lines. Software instructions determine the CMOS out-
put or Schmitt trigger input with pull-high resistor (determined by
pull-high options).
Wake-up options: PD0~PD7
Negative power supply, ground
Bidirectional I/O lines. Software instructions determine the CMOS out-
put or Schmitt trigger input with pull-high resistor (determined by
pull-high options).
