Input Capture or Output Compare Channel Configuration
0 The corresponding channel acts as an input capture.
1 The corresponding channel acts as an output compare.
Force Output Compare Action for Channel 7:4 — 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.
Note: A successful channel 7 output compare overrides any channel 6:4 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.
