Description
4
TCFV
0
R/(W) Overflow Flag
Status flag that indicates that TCNT overflow has
occurred. Only 0 can be written, for flag clearing.
[Setting condition]
• When the TCNT value overflows (changes from
H'FFFF to H'0000 )
• In channel 4, when TCNT-4 is underflowed (H'0001 →
H'0000) in complementary PWM mode.
[Clearing condition]
• When 0 is written to TCFV after reading TCFV = 1
• In channel 4, when DTC is activated by the TCIV
interrupt and the DISEL bit in DTMR of DTC is 0.
3
TGFD
0
R/(W) Input Capture/Output Compare Flag D
Status flag that indicates the occurrence of TGRD input
capture or compare match in channels 0, 3, and 4. Only 0
can be written, for flag clearing. In channels 1 and 2, bit 3
is reserved. It is always read as 0, and should only be
written with 0.
[Setting conditions]
• When TCNT = TGRD and TGRD is functioning as
output compare register
• When TCNT value is transferred to TGRD by input
capture signal and TGRD is functioning as input
capture register
[Clearing conditions]
• When DTC is activated by TGID interrupt and the
DISEL bit of DTMR in DTC is 0
• When 0 is written to TGFD after reading TGFD = 1
