D.13 Output Compare (OC)
MPC555 / MPC556
USER’S MANUAL
The output compare (OC) function generates a rising edge, falling edge, or a toggle of
the previous edge in one of three ways:
where RATIO is a parameter supplied.
This algorithm generates a 50% duty-cycle continuous square wave with each high/
low time equal to the calculated OFFSET. Due to offset calculation, there is an initial
link time before continuous pulse generation begins. See Motorola TPU Progamming
