Convert the channel 0 data word (° F) to BCD and write this to the LED indicator display.
Initialize Channel 0
Program
The use of the masked move instruction with the 0FF mask lets you use outputs 12, 13, 14 and 15 for other
output devices in your system. The seven segment display uses outputs 0 …11.
