R/W Description
R
Reserved
These bits are always read as 0. The write value should
always be 0.
R/(W)*¹ Compare Match/Input Capture Flag U5
Status flag that indicates the occurrence of TGRU_5
input capture or compare match.
[Setting conditions]
• When TCNTU_5 = TGRU_5 and TGRU_5 is
functioning as output compare register
• When TCNTU_5 value is transferred to TGRU_5 by
input capture signal and TGRU_5 is functioning as
input capture register
• When TCNTU_5 value is transferred to TGRU_5 and
TGRU_5 is functioning as a register for measuring the
pulse width of the external input signal. The transfer
timing is specified by the IOC bits in timer I/O control
register U_5 (TIORU_5).*²
[Clearing conditions]
• When DTC is activated by a TGIU_5 interrupt and the
DISEL bit of MRB in DTC is 0
• When 0 is written to CMFU5 after reading CMFU5 = 1
