11.4 Assume PIC18F4321. Write a PIC18F assembly language program at address 0x200 that will generate a square wave on the CCP1 pin using the Compare mode. The square wave will have a period of 20 ms with a 50% duty cycle. Use Timer! internal clock of 4MHz with 1:2 prescale value. 11.4 Assume PIC18F4321.
