Input Capture/Output Compare Flag A
0 [Clearing conditions]
• When DTC is activated by TGIA interrupt while DISEL bit
of MRB in DTC is 0
• When 0 is written to TGFA after reading TGFA = 1
1 [Setting conditions]
• When TCNT = TGRA while TGRA is functioning as output
compare register
• When TCNT value is transferred to TGRA by input capture
signal while TGRA is functioning as input capture register
Input Capture/Output Compare Flag B
0 [Clearing conditions]
• When DTC is activated by TGIB interrupt while DISEL bit of MRB in DTC is 0
• When 0 is written to TGFB after reading TGFB = 1
1 [Setting conditions]
• When TCNT = TGRB while TGRB is functioning as output compare register
• When TCNT value is transferred to TGRB by input capture signal while
TGRB is functioning as input capture register
Input Capture/Output Compare Flag C
0 [Clearing conditions]
• 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
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
Input Capture/Output Compare Flag D
0 [Clearing conditions]
• 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
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
Overflow Flag
0 [Clearing condition]
• When 0 is written to TCFV after reading TCFV = 1
1 [Setting condition]
• When the TCNT value overflows (changes from H'FFFF to H'0000)
Note: * Can only be written with 0 for flag clearing.
