2.3.35 PJ1 / KWJ1 / TXD2 — PORT J I/O Pin 1
PJ1is ageneralpurposeinputoroutputpin.ItcanbeconfiguredtogenerateaninterruptcausingtheMCU
to exit STOP or WAIT mode. It can be configured as the transmit pin TXD of the Serial Communication
Interface 2 (SCI2).
2.3.36 PJ0 / KWJ0 / RXD2 — PORT J I/O Pin 0
PJ0is ageneralpurposeinputoroutputpin.ItcanbeconfiguredtogenerateaninterruptcausingtheMCU
to exit STOP or WAIT mode. It can be configured as the receive pin RXD of the Serial Communication
Interface 2 (SCI2).
2.3.37 PK7 / EWAIT / ROMCTL — Port K I/O Pin 7
PK7 is a general purpose input or output pin. During MCU emulation modes and normal 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. The EWAIT input signal
maintains the external bus access until the external device is ready to capture data (write) or provide data
(read).
2.3.38 PK6 / NOACC / ADDR22 — Port K I/O Pin 6
PK6 is a general purpose input or output pin. During MCU expanded modes of operation, the NOACC
signalisusedtoindicatethatthecurrentbuscycleisanunusedor"free"cycle.Thissignalwillassertwhen
the CPU is not using the bus. This pin also provides the expanded address ADDR22 for the external bus.
In Emulation modes NOACC is available and is time multiplexed with the high address.
2.3.39 PK[5:4] / ADDR[21:20] — Port K I/O Pins [5:4]
PK5-PK4 are general purpose input or output pins. In MCU expanded modes of operation, these pins
provide the expanded address ADDR[21:20] for the external bus.
2.3.40 PK[3:0] / ADDR[19:16] / IQSTAT[3:0] — Port K I/O Pins [3:0]
PK3-PK0 are general purpose input or output pins. In MCU expanded modes of operation, these pins
provide the expanded address ADDR[19:16] for the external bus and carry instruction pipe information.
2.3.41 PM7 / TXCAN3 / TXCAN4 / TXD3 — Port M I/O Pin 7
PM7 is a general purpose input or output pin. It can be configured as the transmit pin TXCAN of the
Motorola Scalable Controller Area Network controller 3 or 4 (CAN3 or CAN4). PM7 can be configured
as the transmit pin TXD3 of the Serial Communication Interface 3 (SCI3).
