MCU_PORT
The MCU_PORT provides signal access between the MCU and the breadboard. This con-
nector is designed to interface directly with the Axiom Manufacturing Project Board through a
60-pin ribbon cable. This connector will also support ribbon-cable connection to the Axiom
Manufacturing MCU Project Board.
KEYPAD / PORT P
The KEYPAD / PORT-P connector supports connection of a passive 12-key or 16-key keypad.
This connector also provides connection directly to Port P on the MCU. Current limit is not
provided on any KEYPAD input and should be provided by the user if needed or desired.

The MCU_PORT provides access to the peripheral
features and I/O lines of the HCS12.
** Note signals with alternate connections on the devel-
opment board:
PA[7..0]/AD[7..0] provide multiplexed address /
data on the expanded mode MCU.
PB[7..0]/AD[7..0] provide multiplexed address /
data on the expanded mode MCU.
PM[1..0]/[TXCAN, RXCAN] CAN channel to
CAN Port transceiver.
PM[5..0] (SPI Port) provides LCD PORT serial
interface.
PS[1..0] COM Port RXD, TXD provides serial
RS-232 interface.
This interface is implemented as a software
key scan. Use pins PP[3..0] as active high
column driver outputs. Use pins PP[7..4] as
row inputs. Each row input will read high
when the associated row is active.
