INTRODUCTION
Before using this module, the user should be familiar with the hardware and software operation
of the target MCU. Refer to the MC9S12C32 User Manual and MC9S12C32 Reference
Manual for details on MCU operation. The module’s purpose is to promote the features of the
MC9S12C32 and to assist the user in quickly developing an application in a known working
environment. Users should be familiar with memory mapping, memory types, and embedded
software design for quick, successful, application development.
The APS12C32SLK Educational Module is a fully assembled, fully functional module
supporting Freescale MC9S12C32 microcontroller. The module comes with a serial cable,
power supply, and an embedded monitor for stand-alone operation. Support software for this
module is provided for Windows 95/98/NT/2000/XP operating systems.
Application development may be performed by using the embedded monitor, or any
compatible BDM cable with supporting host software. The embedded monitor provides an
effective, low cost, debug method. Note that when a BDM cable is used for debugging, the
BDM pod should be powered from an external supply.
GETTING STARTED
Please refer to the APS12C32SLK Quick Start Users Guide to quickly setup the stand-alone
application module or PBS12C32SLK Quick Start Users Guide to get started with the
microcontroller project board (PBMCUSLK).
Operation
The APS12C32SLK module provides input and output features designed to assist embedded
application development. Access to the MCU port signals is available through module
connector J1. This connector may also be used to input power to the module or to output
power to attached modules. RS-232 communications signals may also be input through
connector J1. Care must be exercised when using the J1 to power the module, as only
regulated voltage in the range of +3.3V to +5V should be supplied to this connection. The on-
board regulator provides a fixed +5V voltage to the module.
Five user option jumpers and 3 cut-traces control module operation. Enabling a user option
requires installing a jumper across the associated header pins. Removing the jumper disables
the associated option. An option enabled by a cut-trace can be disabled by removing the
circuit trace between the cut-trace component pads. Use a sharp knife to cut the embedded
circuit trace. Be careful not to damage adjacent circuitry. To re-enable the option, simply
install a 1206 sized 0-ohm resistor or piece of wire across the cut-trace component pads.
