Description
PA0~PA7
I/O
Pull-low
Pull-high
Wake-up
CMOS/NMOS/PMOS
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
Pull-low resistor options: PA0~PA3
CMOS/NMOS/PMOS options: PA0~PA7
Falling edge wake-up options: PA0~PA1, PA4~PA7
Rising and falling edge wake-up options: PA2~PA3
PB2, PB3
I/O
Pull-high
Pull-low
Bidirectional 8-bit input/output port. Software instructions determine the
CMOSoutputorSchmitttriggerinputwithpull-highresistor(determined
by pull-high options).
Pull-low resistor for options: PB2, PB3
PB4, PB7
I/O
Pull-high
Wake-up
Bidirectional 8-bit input/output port. Software instructions determine the
CMOSoutputorSchmitttriggerinputwithpull-highresistor(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
VSS
Negative power supply, ground
RES
I
Schmitt trigger reset input. Active low.
