PH7 / KWH7 / SS2 / TXD5 — Port H I/O Pin 7
PH7 is a general-purpose input or output pin. It can be congured to generate an interrupt causing the
MCU to exit stop or wait mode. It can be congured as slave select pin SS of the serial peripheral
interface 2 (SPI2). It can be congured 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 congured to generate an interrupt causing the
MCU to exit stop or wait mode. It can be congured as serial clock pin SCK of the serial peripheral
interface 2 (SPI2). It can be congured 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 congured to generate an interrupt causing the
MCU to exit stop or wait mode. It can be congured as master output (during master mode) or slave input
pin (during slave mode) MOSI of the serial peripheral interface 2 (SPI2). It can be congured 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 congured to generate an interrupt causing the
MCU to exit stop or wait mode. It can be congured as master input (during master mode) or slave output
(during slave mode) pin MISO of the serial peripheral interface 2 (SPI2). It can be congured 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 congured to generate an interrupt causing the
MCU to exit stop or wait mode. It can be congured 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 congured to generate an interrupt causing the
MCU to exit stop or wait mode. It can be congured 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 congured to generate an interrupt causing the
MCU to exit stop or wait mode. It can be congured as master output (during master mode) or slave input
pin (during slave mode) MOSI of the serial peripheral interface 1 (SPI1).
