• Manufacturer Part Number: AN2818
• Description: Romeo2 Monitor for the MC68HC908AP64 MCU
• Manufacturer: Freescale Semiconductor / Motorola

To start the monitor:
You should now see the screen shown in
Demo Board.
This screen shows the state of various pins that connect between the Romeo2 RF module and the
MC68HC908AP64 Demo Board. It also displays the contents of Romeo2's internal registers and displays
the state of each bit in these registers.
Commands can be typed in the terminal program window. Type HELP <return> for a complete list of
commands (see

1. Configure the terminal program for 9600 baud, eight data bits, no parity, one stop bit, no flow
2. Connect MC68HC908AP64 Demo Board to the PC comm. port using the 9-pin D connector.
3. Start the terminal program (in Hyperterminal, click the 'Connect' icon on the toolbar at the top of

Each Romeo2 RF module is hard-wired to a specific carrier frequency —
315 MHz, 434 MHz, 838 MHz, 915 MHz. Ensure that you program the CF
bit in register CR1 to the correct value for your RF module.
