2.3.18 PE2 / R/W—Port E I/O Pin 2
PE2 is a general purpose input or output pin. In MCU expanded modes of operations, this pin drives the
read/write output signal for the external bus. It indicates the direction of data on the external bus.
2.3.19 PE1 / IRQ — Port E Input Pin 1
PE1 is a general purpose input pin and the maskable interrupt request input that provides a means of
applying asynchronous interrupt requests. This will wake up the MCU from STOP or WAIT mode.
2.3.20 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.
2.3.21 PH7 / KWH7 / SS2 — Port H I/O Pin 7
PH7isageneralpurposeinputoroutputpin.ItcanbeconfiguredtogenerateaninterruptcausingtheMCU
to exit STOP or WAIT mode. It can be configured as slave select pin SS of the Serial Peripheral Interface
2 (SPI2).
2.3.22 PH6 / KWH6 / SCK2 — Port H I/O Pin 6
PH6isageneralpurposeinputoroutputpin.ItcanbeconfiguredtogenerateaninterruptcausingtheMCU
toexitSTOPorWAITmode.ItcanbeconfiguredasserialclockpinSCKoftheSerialPeripheralInterface
2 (SPI2).
2.3.23 PH5 / KWH5 / MOSI2 — Port H I/O Pin 5
PH5isageneralpurposeinputoroutputpin.ItcanbeconfiguredtogenerateaninterruptcausingtheMCU
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
PH4isageneralpurposeinputoroutputpin.ItcanbeconfiguredtogenerateaninterruptcausingtheMCU
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
PH3isageneralpurposeinputoroutputpin.ItcanbeconfiguredtogenerateaninterruptcausingtheMCU
to exit STOP or WAIT mode. It can be configured as slave select pin SS of the Serial Peripheral Interface
1 (SPI1).
