OCF1
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.
