Each bit can be configured as a wake-up input by ROM code option. The input or output mode is controlled by PAC (PA control register). Pull-low Pull-high resistor options: PA0~PA7 Pull-high I/O Pull-low resistor options: PA0~PA3 Wake-up CMOS/NMOS/PMOS CMOS/NMOS/PMOS options: PA0~PA7 Falling edge wake-up options: PA0~PA1, PA4~PA7 Rising and falling edge wake-up options: PA2~PA3 Pull-high Pull-low 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). Pull-low resistor for options: PB2, PB3 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). The PB can be used as analog input of the analog to digital converter (determined by options). Falling edge wake-up options: PB4, PB7 Negative power supply, ground Schmitt trigger reset input.
