Device User Guide — 9S12C128DGV1/D V01.05

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

PM0 is a general purpose input or output pin and the receive pin, RXCAN, of the CAN module if available.
