When TCNT overflows from H'FFFF to H'0000
Read OVF when OVF = 1, then write 0 in OVF
TCNT = GRD when GRD functions as an output
compare register
The TCNT value is transferred to GRD by an input
capture signal when GRD functions as an input
capture register
Read IMFD when IMFD = 1, then write 0 in IMFD
TCNT = GRC when GRC functions as an output
compare register
The TCNT value is transferred to GRC by an input
capture signal when GRC functions as an input
capture register
Read IMFC when IMFC = 1, then write 0 in IMFC
