MC9S12DT256 Device User Guide — V03.03
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
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).
2.3.22 PH6 / KWH6 / SCK2 — 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).
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).
