R/W Description
7 OVF 0 R/(W)* Timer Overflow
This flag indicates a TDPCNT overflow.
[Setting condition]
• TDPCNT overflow (H'FFFF changes to H'0000)
[Clearing condition]
• Reading OVF when OVF = 1 and then writing 0 to OVF
6 TWDMXOVF 0 R/(W)* Pulse Width Upper Limit Overflow
This flag indicates that the waveform pulse width measured
in cycle measurement mode has exceeded the upper limit
specified in TDPWDMX.
[Setting condition]
• When TDPICR is greater than TDPWDMX
[Clearing condition]
• Reading TWDMXOVF when TWDMXOVF = 1 and then
writing 0 to TWDMXOVF
5 TWDMNUDF 0 R/(W)* Pulse Width Lower Limit Underflow
This flag indicates that the waveform pulse width measured
in cycle measurement mode is below the lower limit
specified in TDPWDMN.
[Setting condition]
• When TDPICR is less than TDPWDMN
[Clearing condition]
• Reading TWDMNUDF when TWDMNUDF = 1 and then
writing 0 to TWDMNUDF
4 TPDMXOVF 0 R/(W)* Cycle Upper Limit Overflow
This flag indicates that the waveform period measured in
cycle measurement mode has exceeded the upper limit
specified in TDPPDMX.
[Setting condition]
• When TDPICR is greater than TDPPDMX
[Clearing condition]
• Reading TPDMXOVF when TPDMXOVF = 1 and then
writing 0 to TPDMXOVF
