Output Compare (OC)
The output compare (OC) function generates a rising edge, falling edge, or a toggle of the previous edge:
immediately upon RCPU initiation (generating a pulse with a length equal to a programmable delay time),
after a programmable delay time, or continuously. Upon receiving a link from a channel, OC references,
without RCPU interaction, a specifiable period and calculates an offset that is equal to the period
x
the
ratio, where the ratio is a supplied parameter.
This algorithm generates, with each high/low time, a 50% duty-cycle continuous square equal to the
calculated offset. Due to offset calculation, there is an initial link time before continuous pulse generation
begins. See Freescale TPU Progamming Note
Output Compare TPU Function (OC), (TPUPN12/D).
