1.5.6.12
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 output (ECS).
During MCU expanded modes of operation, 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 all other modes the reset state of the ROMON bit is as follows:
1.5.6.13
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.
1.5.6.14
PL7–PL4 are general-purpose input or output pins. They can be configured as frontplane segment driver
outputs FP31–FP28 of the LCD module or analog inputs for the analog-to-digital converter.
1.5.6.15
PL3–PL0 are general-purpose input or output pins. They can be configured as frontplane segment driver
outputs FP19–FP16 of the LCD module or analog inputs for the analog-to-digital converter.
1.5.6.16
PM5 is a general-purpose input or output pin. It can be configured as the transmit pin TXCAN1 of the
scalable controller area network controller 1 (CAN1)
1.5.6.17
PM4 is a general-purpose input or output pin. It can be configured as the receive pin RXCAN1 of the
scalable controller area network controller 1 (CAN1)
1.5.6.18
PM3 is a general-purpose input or output pin. It can be configured as the transmit pin TXCAN0 of the
scalable controller area network controller 0 (CAN0)
