Chapter 1 MC9S12KG128 Device Overview (MC9S12KG128V1)

1.2.2.17 PE0 / XIRQ â Port E Input Pin 0

PE0 is a general purpose input pin and the non-maskable interrupt request input that provides a means of

applying asynchronous interrupt requests. This will wake up the MCU from STOP or WAIT mode.

1.2.2.18 PH7 / KWH7 / SS2 â Port H I/O Pin 7

PH7 is a general purpose input or output pin. It can be conï¬gured to generate an interrupt causing the MCU

to exit STOP or WAIT mode. It can be conï¬gured as slave select pin SS of the Serial Peripheral Interface 2

(SPI2).

1.2.2.19 PH6 / KWH6 / SCK2 â Port H I/O Pin 6

PH6 is a general purpose input or output pin. It can be conï¬gured to generate an interrupt causing the MCU

to exit STOP or WAIT mode. It can be conï¬gured as serial clock pin SCK of the Serial Peripheral

Interface 2 (SPI2).

1.2.2.20 PH5 / KWH5 / MOSI2 â Port H I/O Pin 5

PH5 is a general purpose input or output pin. It can be conï¬gured to generate an interrupt causing the MCU

to exit STOP or WAIT mode. It can be conï¬gured as master output (during master mode) or slave input

pin (during slave mode) MOSI of the Serial Peripheral Interface 2 (SPI2).

1.2.2.21 PH4 / KWH4 / MISO2 â Port H I/O Pin 2

PH4 is a general purpose input or output pin. It can be conï¬gured to generate an interrupt causing the MCU

to exit STOP or WAIT mode. It can be conï¬gured as master input (during master mode) or slave output

(during slave mode) pin MISO of the Serial Peripheral Interface 2 (SPI2).

1.2.2.22 PH3 / KWH3 / SS1 â Port H I/O Pin 3

PH3 is a general purpose input or output pin. It can be conï¬gured to generate an interrupt causing the MCU

to exit STOP or WAIT mode. It can be conï¬gured as slave select pin SS of the Serial Peripheral Interface 1

(SPI1).

1.2.2.23 PH2 / KWH2 / SCK1 â Port H I/O Pin 2

PH2 is a general purpose input or output pin. It can be conï¬gured to generate an interrupt causing the MCU

to exit STOP or WAIT mode. It can be conï¬gured as serial clock pin SCK of the Serial Peripheral

Interface 1 (SPI1).

1.2.2.24 PH1 / KWH1 / MOSI1 â Port H I/O Pin 1

PH1 is a general purpose input or output pin. It can be conï¬gured to generate an interrupt causing the MCU

to exit STOP or WAIT mode. It can be conï¬gured as master output (during master mode) or slave input

pin (during slave mode) MOSI of the Serial Peripheral Interface 1 (SPI1).
