Description
7:0
FOC[7:0]
Note: Force Output Compare Action for Channel 7:0 — A write to this register with the corresponding data
bit(s) set causes the action which is programmed for output compare “x” to occur immediately. The action
taken is the same as if a successful comparison had just taken place with the TCx register except the
interrupt flag does not get set. A channel 7 event, which can be a counter overflow when TTOV[7] is set or
a successful output compare on channel 7, overrides any channel 6:0 compares. If forced output compare
on any channel occurs at the same time as the successful output compare then forced output compare
action will take precedence and interrupt flag won’t get set.
