Chapter 1 MC9S12KG128 Device Overview (MC9S12KG128V1)
For all other modes the reset state of the ROMON bit is as follows:
• Special single: ROMCTL = 1
• Normal single: ROMCTL = 1
• Emulation expanded wide: ROMCTL = 0
• Emulation expanded narrow: ROMCTL = 0
• Special test: ROMCTL = 0
• Peripheral test: ROMCTL = 1
1.2.2.30 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.
1.2.2.31 PM7 / TXCAN4 — 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
Scalable Controller Area Network controllers 4 (CAN4).
1.2.2.32 PM6 / RXCAN4 — Port M I/O Pin 6
PM6 is a general purpose input or output pin. It can be configured as the receive pin RXCAN of the
Scalable Controller Area Network controllers 4 (CAN4).
1.2.2.33 PM5 / TXCAN0 / TXCAN4 / SCK0 — Port M I/O Pin 5
PM5 is a general purpose input or output pin. It can be configured as the transmit pin TXCAN of the
Scalable Controller Area Network controllers 0 or 4 (CAN0 or CAN4). It can be configured as the serial
clock pin SCK of the Serial Peripheral Interface 0 (SPI0).
1.2.2.34 PM4 / RXCAN0 / RXCAN4/ MOSI0 — Port M I/O Pin 4
PM4 is a general purpose input or output pin. It can be configured as the receive pin RXCAN of the
Scalable Controller Area Network controllers 0 or 4 (CAN0 or CAN4). It can be configured as the master
output (during master mode) or slave input pin (during slave mode) MOSI for the Serial Peripheral
Interface 0 (SPI0).
1.2.2.35 PM3 / TXCAN0 / SS0 — Port M I/O Pin 3
PM3 is a general purpose input or output pin. It can be configured as the transmit pin TXCAN of the
Scalable Controller Area Network controller 0 (CAN0). It can be configured as the slave select pin SS of
the Serial Peripheral Interface 0 (SPI0).
