GRB Function
GRB is an output
compare register
GRB is an input
capture register
No output at compare match
0 output at GRB compare match^*1
1 output at GRB compare match^*1
Output toggles at GRB compare match^*1,*2
GRB captures rising edge of input
GRB captures falling edge of input
GRB captures both edges of input
Notes: 1. After a reset, the output is 0 until the first compare match.
2. Channel 2 output cannot be toggled by compare match.
This setting selects 1output instead.
