IEDG1 – Input Edge
Value of input edge determines which level transition on TCAP1 pin will
trigger free running counter transfer to the input capture register 1.
1 = Positive edge
0 = Negative edge
IEDG2 – Input Edge
Value of input edge determines which level transition on TCAP2 pin will
trigger free running counter transfer to the input capture register 2.
1 = Positive edge
0 = Negative edge
CLK21 – Output Compare 2 clocks output latch 1
If this bit is set to 1, a successful compare of compare register 2 loads
the OLVL2 bit to the output latch 1. This feature can be used to get
output pulses as short as E/4 while using only one interrupt.
