2.2.23 PH2 / KWH2 — 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.
2.2.24 PH1 / KWH1 — 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.
2.2.25 PH0 / KWH0 — 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.
2.2.26 PJ7 / KWJ7 / SCL — Port J I/O Pins 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 serial clock pin SCL of the IIC module.
2.2.27 PJ6 / KWJ6 / SDA — Port J I/O Pins 6
PJ6 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 serial data pin SDA of the IIC module.
2.2.28 PJ[1:0] / KWJ[1:0] — Port J I/O Pins [1:0]
PJ1 and 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.
2.2.29 PK7 / ECS / ROMCTL — Port K I/O Pin 7
PK7 is a general purpose input or output pin. During MCU expanded modes of operation, this pin is used
as the emulation chip select output (ECS). While configurating MCU expanded modes this pin is used to
enable the Flash EEPROM memory in the memory map (ROMCTL). At the rising edge of RESET, the
state of this pin is latched to the ROMON bit. For a complete list of modes refer to 4.2 Chip Configuration
2.2.30 PK[5:0] / XADDR[19:14] — Port K I/O Pins [5:0]
PK5-PK0 are general purpose input or output pins. In MCU expanded modes of operation, these pins
provide the expanded address XADDR[19:14] for the external bus.
