This bit determines which type of level transition on the ICAP2 pin
triggers the capture.
0: A falling edge triggers the capture
1: A rising edge triggers the capture
This bit determines which type of level transition on the external
clock pin EXTCLK triggers the counter register.
0: A falling edge triggers the counter register
1: A rising edge triggers the counter register
0: No input capture (reset value)
1: An input capture has occurred on the ICAP1 pin or the counter
has reached the OC2R value in PWM mode. To clear this bit, first
read the SR register, then read or write the low byte of the IC1R
(IC1LR) register.
0: No match (reset value)
1: The content of the free running counter has matched the content
of the OC1R register. To clear this bit, first read the SR register, then
read or write the low byte of the OC1R (OC1LR) register.
0: No timer overflow (reset value)
1: The free running counter rolled over from FFFFh to 0000h. To
clear this bit, first read the SR register, then read or write the low
byte of the CR (CLR) register.
Note: Reading or writing the ACLR register does not clear TOF
0: No input capture (reset value)
1: An input capture has occurred on the ICAP2 pin. To clear this bit,
first read the SR register, then read or write the low byte of the IC2R
(IC2LR) register.
