2.3.21 PE0 / XIRQ — 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.

2.3.22 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).

2.3.23 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).

2.3.24 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).

2.3.25 PH4 / KWH4 / MISO2 / RXD4 — Port H I/O Pin 2

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).

2.3.26 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).

2.3.27 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).
