Decoding of commands typed into the PC terminal program is done in the SCIRx() routine. This routine

is called each time the MCU receives a character from the PC keyboard. It stores characters in a buffer

until a carriage return is detected. It then decodes the buffer and performs the required function for each

message.

When the SEND command is used, the monitor uses the MCU’s 16-bit timer to generate the Manchester

encoded data on the timer channel 1 output pin.

The monitor uses the following MCU resources.

It should be possible to port the code to another MCU by changing the register definitions and some other

definitions at the beginning of the code.
