Pinout and Signal Description
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.
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.
PK7 / ECS /
ROMONE — 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). During MCU Normal Expanded and Emulation 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 determines the state of the ROMON bit (MISC register) according to
Table 24 in page 129. See page 128 for details about the ROMON bit.
PP7 / PWM7 — Port PP7 is a general purpose input or output pin. It can be configured as
P I/O Pin 7
Pulse Width Modulator (PWM) channel 7 output.
PP6 / PWM6 — Port PP6 is a general purpose input or output pin. It can be configured as
P I/O Pin 6
Pulse Width Modulator (PWM) channel 6 output.
PP5 / PWM5 — Port PP5 is a general purpose input or output pin. It can be configured as
P I/O Pin 5
Pulse Width Modulator (PWM) channel 5 output.
PP4 / PWM4 — Port PP4 is a general purpose input or output pin. It can be configured as
P I/O Pin 4
Pulse Width Modulator (PWM) channel 4 output.
PP3 / PWM3 — Port PP3 is a general purpose input or output pin. It can be configured as
P I/O Pin 3
Pulse Width Modulator (PWM) channel 3 output.
