MC9S12H256 Device User Guide — V01.20
2.3.15 PE2 / FP20 / R/W — Port E I/O Pin 2
PE2 is a general purpose input or output pin. It can be configured as frontplane segment driver output FP20
of the LCD module. In MCU expanded modes of operations, this pin performs the read/write output signal
for the external bus. It indicates the direction of data on the external bus.
2.3.16 PE1 / IRQ — Port E Input Pin 1
PE1 is a general purpose input pin and also 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.
2.3.17 PE0 / XIRQ — Port E Input Pin 0
PE0 is a general purpose input pin and also 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.
2.3.18 PH[7:0] / KWH[7:0] — Port H I/O Pins [7:0]
PH7-PH0 are general purpose input or output pins. They can be configured to generate an interrupt causing
the MCU to exit STOP or WAIT mode.
2.3.19 PJ[3:0] / KWJ[3:0] — Port J I/O Pins [3:0]
PJ3-PJ0 are general purpose input or output pins. They can be configured to generate an interrupt causing
the MCU to exit STOP or WAIT mode.and are shared with the interrupt function.
2.3.20 PK7 / FP23 / ECS / ROMONE — Port K I/O Pin 7
PK7 is a general purpose input or output pin. It can be configured as frontplane segment driver output FP23
of the LCD module. During MCU expanded modes of operation, this pin is used as the emulation chip
select signal (ECS). During reset of the MCU to normal expanded modes of operation, this pin is used to
enable the Flash EEPROM memory in the memory map (ROMONE). At the rising edge of RESET, the
state of this pin is latched to the ROMON bit.
2.3.21 PK[3:0] / BP[3:0] / XADDR[17:14] — Port K I/O Pins [3:0]
PK3-PK0 are general purpose input or output pins. They can be configured as backplane segment driver
outputs BP3-BP0 of the LCD module. In MCU expanded modes of operation, these pins provide the
expanded address XADDR[17:14] for the external bus.
