Checking Output

To check the serial output from the PLL_Demo program, connect a serial cable from COM1 on the board to an unused COM port on your development PC. Use a terminal emulation program, such as Microsoft Windows HyperTerminal, to display the serial data on your PC monitor.

To start the Microsoft Windows HyperTerminal application, select Start - Programs - Accessories - Communication - HyperTerminal.

  1. Enter a Name for the new connection, for example: MCBXC167.


  2. Select the PC COM port COM1 in Connect Using.


  3. Select 19200 Bits per second, 8 Data bits, Parity None, Stop bits 1 and Flow control None.


  4. Click OK. The text message The CPU currently runs at 20000000 Hz displays from the MCBXC167 Board, where 20000000 Hz is a value that changes as the PLL settings change.
