PH7 / KWH7 / SS2 / TXD5 — Port H I/O Pin 7

PH7 is a general-purpose input or output pin. It can be conﬁgured to generate an interrupt causing the

MCU to exit stop or wait mode. It can be conﬁgured as slave select pin SS of the serial peripheral

interface 2 (SPI2). It can be conﬁgured as the transmit pin TXD of serial communication interface 5

(SCI5).

1.2.3.26

PH6 / KWH6 / SCK2 / RXD5 — Port H I/O Pin 6

PH6 is a general-purpose input or output pin. It can be conﬁgured to generate an interrupt causing the

MCU to exit stop or wait mode. It can be conﬁgured as serial clock pin SCK of the serial peripheral

interface 2 (SPI2). It can be conﬁgured as the receive pin (RXD) of serial communication interface 5

(SCI5).

1.2.3.27

PH5 / KWH5 / MOSI2 / TXD4 — Port H I/O Pin 5

PH5 is a general-purpose input or output pin. It can be conﬁgured to generate an interrupt causing the

MCU to exit stop or wait mode. It can be conﬁgured as master output (during master mode) or slave input

pin (during slave mode) MOSI of the serial peripheral interface 2 (SPI2). It can be conﬁgured as the

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

1.2.3.28

PH4 / KWH4 / MISO2 / RXD4 — Port H I/O Pin 4

PH4 is a general-purpose input or output pin. It can be conﬁgured to generate an interrupt causing the

MCU to exit stop or wait mode. It can be conﬁgured as master input (during master mode) or slave output

(during slave mode) pin MISO of the serial peripheral interface 2 (SPI2). It can be conﬁgured as the receive

pin RXD of serial communication interface 4 (SCI4).

1.2.3.29

PH3 / KWH3 / SS1 — Port H I/O Pin 3

PH3 is a general-purpose input or output pin. It can be conﬁgured to generate an interrupt causing the

MCU to exit stop or wait mode. It can be conﬁgured as slave select pin SS of the serial peripheral

interface 1 (SPI1).

1.2.3.30

PH2 / KWH2 / SCK1 — Port H I/O Pin 2

PH2 is a general-purpose input or output pin. It can be conﬁgured to generate an interrupt causing the

MCU to exit stop or wait mode. It can be conﬁgured as serial clock pin SCK of the serial peripheral

interface 1 (SPI1).

1.2.3.31

PH1 / KWH1 / MOSI1 — Port H I/O Pin 1

PH1 is a general-purpose input or output pin. It can be conﬁgured to generate an interrupt causing the

MCU to exit stop or wait mode. It can be conﬁgured as master output (during master mode) or slave input

pin (during slave mode) MOSI of the serial peripheral interface 1 (SPI1).
