2.3.23 PH5 / KWH5 / MOSI2 — 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).
2.3.24 PH4 / KWH4 / MISO2 — 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).
2.3.25 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).
2.3.26 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).
2.3.27 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).
2.3.28 PH0 / KWH0 / MISO1 — Port H I/O Pin 0
PH0 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 1 (SPI1).
2.3.29 PJ7 / KWJ7 / TXCAN4 / SCL — PORT J I/O Pin 7
PJ7 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 the transmit pin TXCAN for the Motorola Scalable
Controller Area Network controller 4 (CAN4) or the serial clock pin SCL of the IIC module.
