Chapter 1 Device Overview MC9S12XE-Family

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 as a keypad wakeup input. 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 as a keypad wakeup input. It can be

conï¬gured as slave select pin SS of the serial peripheral interface 1 (SPI1). It can also be conï¬gured as the

transmit pin TXD of serial communication interface 7 (SCI7).

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 as a keypad wakeup input. It can be

conï¬gured as serial clock pin SCK of the serial peripheral interface 1 (SPI1). It can be conï¬gured as the

receive pin RXD of serial communication interface 7 (SCI7).

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 as a keypad wakeup input. 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). It can also be conï¬gured as the transmit pin TXD of serial

communication interface 6 (SCI6).

1.2.3.32 PH0 / KWH0 / MISO1 â Port H I/O Pin 0

PH0 is a general-purpose input or output pin. It can be conï¬gured as a keypad wakeup input. It can be

conï¬gured as master input (during master mode) or slave output (during slave mode) pin MISO of the

serial peripheral interface 1 (SPI1). It can be conï¬gured as the receive pin RXD of serial communication

interface 6 (SCI6).

1.2.3.33 PJ7 / KWJ7 / TXCAN4 / SCL0 / TXCAN0â PORT J I/O Pin 7

PJ7 is a general-purpose input or output pin. It can be conï¬gured as a keypad wakeup input. It can be

conï¬gured as the transmit pin TXCAN for the scalable controller area network controller 0 or 4 (CAN0 or

CAN4) or as the serial clock pin SCL of the IIC0 module.

1.2.3.34 PJ6 / KWJ6 / RXCAN4 / SDA0 / RXCAN0 â PORT J I/O Pin 6

PJ6 is a general-purpose input or output pin. It can be conï¬gured as a keypad wakeup input. It can be

conï¬gured as the receive pin RXCAN for the scalable controller area network controller 0 or 4 (CAN0 or

CAN4) or as the serial data pin SDA of the IIC0 module.
