Power Connectors
Power connectors J1 and TB1 provide power input to the board. Voltage input should be lim-
ited to the range of +6VDC to +16VDC with +9VDC typical. Voltage should be applied to the
board at either J1 or TB1 but not both. Applying input voltage to both input connectors at the
same time will cause a supply conflict and damage the CML-12C32 may result.
Connector J1 accepts a standard 2.1mm barrel plug connector with positive voltage center.
Connector TB1 accepts 18G – 24G solid copper wire. TB1 may also be used to gain access to
on-board power levels +Vin, GND, or +5VDC for off-board use. The +5VDC output may be
used to power off-board circuitry if desired. However, the voltage regulator output is internally
limited to 250 mA.
BUS_PORT
The BUS_PORT provides access to Port E signal and to latched address signals. Care should
be taken when using these signals. Excessive load may adversely affect MCU operation.
BDM PORT
The BDM port is a 6-pin header compatible with the Motorola Background Debug Mode (BDM)
Pod. This allows the connection of a background debugger for software development, pro-
gramming and debugging in real-time without using HC12 I/O resources.
A Background Debug Module is available from the Axiom Manufacturing.
