2.3.19 PP[5:0] / KWP[5:0] / PW[5:0] — Port P I/O Pins [5:0]
PP[5:0] are general purpose input or output pins, shared with the keypad interrupt function. When
configured as inputs, they can generate interrupts causing the MCU to exit STOP or WAIT mode.
PP[5:0] are also shared with the PWM output signals, PW[5:0]. Pins PP[2:0] are only available in the 80
pin package version. Pins PP[4:3] are not available in the 48 pin package version.
2.3.20 PJ[7:6] / KWJ[7:6] — Port J I/O Pins [7:6]
PJ[7:6] are general purpose input or output pins, shared with the keypad interrupt function. When
configured as inputs, they can generate interrupts causing the MCU to exit STOP or WAIT mode. These
pins are not available in the 48 pin package version nor in the 52 pin package version.
2.3.21 PM5 / SCK — Port M I/O Pin 5
PM5 is a general purpose input or output pin and also the serial clock pin SCK for the Serial Peripheral
Interface (SPI).
2.3.22 PM4 / MOSI — Port M I/O Pin 4
PM4 is a general purpose input or output pin and also the master output (during master mode) or slave
input (during slave mode) pin for the Serial Peripheral Interface (SPI).
2.3.23 PM3 / SS — Port M I/O Pin 3
PM3 is a general purpose input or output pin and also the slave select pin SS for the Serial Peripheral
Interface (SPI).
2.3.24 PM2 / MISO — Port M I/O Pin 2
PM2 is a general purpose input or output pin and also the master input (during master mode) or slave
output (during slave mode) pin for the Serial Peripheral Interface (SPI).
2.3.25 PM1 / TXCAN — Port M I/O Pin 1
PM1 is a general purpose input or output pin and the transmit pin, TXCAN, of the CAN module if
available.
2.3.26 PM0 / RXCAN — Port M I/O Pin 0
