Serial Monitor Operation
A serial binary monitor is loaded in the MCU internal flash memory. Press and hold SW1 while
pressing the RESET button or applying power. This section provides a brief description of this
serial monitor operation. Refer to application note AN2548 for complete details on the serial
monitor operation. This application note may be found on the Support CD received with the
module or from the Freescale web site.

NOTE: Although the monitor does not support external memory, the user can enable external
memory accesses in the unfilled areas of the memory map.
The 2K-byte serial monitor program provides an RS-232 serial interface to a host PC. Serial
data rate is 115.2K bps. The monitor is compatible with Metrowerks CodeWarrior
