Serial Monitor Demo
The following procedure shows how to load code into the demo board using the serial monitor program
that resides in the MC9S08GB60 memory.
The serial monitor can be used for much more than just programming new code without a special debug
pod. Many debug operations (memory modify, breakpoints, real-time bug traces, etc.) can also be run
over the serial cable while in this mode. Refer to application note AN2140 for more information on the
serial monitor.
