APPENDIX A
HCS12 SERIAL MONITOR OPERATION
This CML-12C32 contains the HCS12 Serial Monitor instead of the MON12 monitor mentioned in the User Guide.
This addendum provides a brief description of this serial monitor program. Further details may be found in Appli-
cation Note AN2548 from Freescale Semiconductor. This board also contains a small demo program that flashes
LED1 and LED2 has been loaded to simulate application code startup.
The 2K byte serial monitor program provides RS-232 serial interface to a host PC. The monitor is compatible with
Metrowerks CodeWarrior and other serial monitor interface IDE’s. It is not compatible with ASCII interface pro-
grams such as hyperterm or AxIDE. The monitor supports 23 primitive commands to control the target MCU. To
allow a user to specify the address of each interrupt service routine, this monitor redirects interrupt vectors to an
unprotected portion of FLASH just before the protected monitor program.
The monitor uses the SCI0 serial interface to communicate with the host PC. The monitor must have exclusive
use of the serial port to work correctly. This monitor accommodates RS-232 serial communications through SCI0
at 115.2 K bps.

NOTE: Although the monitor does not support external memory, the user can enable external
memory accesses in the unfilled areas of the memory map.
CONFIGURATION
The CML-12C32 boots to user application code out of RESET if the pseudo-reset (F7FE:F7FF) vector is pro-
grammed. Pressing SW1 after user application code executes has no effect. A small demo program to flash
LED1 and LED2 has been preloaded at the factory.
To boot to the serial monitor, simply press and hold SW1 while applying power or pressing the RESET button.
The CML-12C32 will boot to monitor mode if the pseudo-reset vector is not programmed also.
