Chapter 1 Device Overview MC9S12XD-Family

1.2.3.25 PH7 / KWH7 / SS2 / TXD5 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). It can be conï¬gured as the transmit pin TXD of serial communication interface 5

(SCI5).

1.2.3.26 PH6 / KWH6 / SCK2 / RXD5 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). It can be conï¬gured as the receive pin (RXD) of serial communication interface 5

(SCI5).

1.2.3.27 PH5 / KWH5 / MOSI2 / TXD4 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). It can be conï¬gured as the

transmit pin TXD of serial communication interface 4 (SCI4).

1.2.3.28 PH4 / KWH4 / MISO2 / RXD4 â Port H I/O Pin 4

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). It can be conï¬gured as the receive

pin RXD of serial communication interface 4 (SCI4).

1.2.3.29 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).

1.2.3.30 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).

1.2.3.31 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).
