Troubleshooting
Monitor Resets to Initial State Randomly
If you have enabled the Tango3 module power amplifier (PA = 1) and are using long cables to provide
power to the MC9S08RG60 board, the RF transmission may couple onto the power supply cables and
cause problems for the MCU. You should use short power supply cables, or place ferrite filters on the
power supply cables, if this problem occurs.
Tango3 Monitor Source Code
The Tango3 monitor was written using the C programming language. Full source code is supplied in file
AN2777SW.zip, which can be downloaded from www.freescale.com.
Modifying Tango3 Monitor
The Tango3 monitor program has a simple structure. It has been written to allow easy porting to other
MCUs. The code is liberally commented and should be easy to understand.
