R/W
Description
This flag indicates that the TCMCNT has overflowed.
[Setting condition]
Overflow of TCMCNT (change in value from H'FFFF to
H'0000)
[Clearing condition]
Reading OVF when OVF = 1 and then writing 0 to OVF.
This flag indicates that the measured number of cycles of
the waveform for measurement in cycle measurement mode
has reached the upper limit set in TCMMLCM, causing an
overflow.
[Setting condition]
A greater value for TCMICR than TCMMLCM
[Clearing condition]
Reading MAXOVF when MAXOVF = 1 and then writing 0 to
MAXOVF
[Setting condition]
When the values in TCMCNT and TCMMLCM match.
[Clearing condition]
Reading CMF when CMF = 1 and then writing 0 to CMF
Note: CMF is not set in cycle measurement mode, even
When bits CKS2 to CKS0 in TCMCR are set to B'111, this
bit selects the edge for counting of external count clock
edge.
0: Count falling edges of the external clock.
1: Count rising edges of the external clock.
External Clock Edge Select
when the values in TCMCNT and TCMMLCM match.
