Bit 4—Overflow Flag (TCFV): Status flag that indicates that TCNT overflow has occurred.
Bit 4
TCFV
0
1
Description
[Clearing condition]
When 0 is written to TCFV after reading TCFV = 1
[Setting condition]
When the TCNT value overflows (changes from H'FFFF to H'0000 )
(Initial value)
Bit 3—Input Capture/Output Compare Flag D (TGFD): Status flag that indicates the occurrence of TGRD input
capture or compare match in channels 0 and 3.
In channels 1, 2, 4, and 5, bit 3 is reserved. It is always read as 0 and cannot be modified.
Bit 3
TGFD
0
1
Description
[Clearing conditions]
(Initial value)
• When DTC is activated by TGID interrupt while DISEL bit of MRB in DTC is 0
• When 0 is written to TGFD after reading TGFD = 1
[Setting conditions]
• When TCNT = TGRD while TGRD is functioning as output compare register
• When TCNT value is transferred to TGRD by input capture signal while TGRD is
functioning as input capture register
Bit 2—Input Capture/Output Compare Flag C (TGFC): Status flag that indicates the occurrence of TGRC input
capture or compare match in channels 0 and 3.
In channels 1, 2, 4, and 5, bit 2 is reserved. It is always read as 0 and cannot be modified.
Bit 2
TGFC
0
1
Description
[Clearing conditions]
(Initial value)
• When DTC is activated by TGIC interrupt while DISEL bit of MRB in DTC is 0
• When 0 is written to TGFC after reading TGFC = 1
[Setting conditions]
• When TCNT = TGRC while TGRC is functioning as output compare register
• When TCNT value is transferred to TGRC by input capture signal while TGRC is
functioning as input capture register
