Bit Bit Name Initial Value R/W
4 TCFV 0
3 TGFD 0
2 TGFC 0
Description
R/(W)* Overflow Flag
Status flag that indicates that TCNT overflow has
occurred.
[Setting condition]
When the TCNT value overflows (change from H'FFFF to
H'0000)
[Clearing condition]
When 0 is written to TCFV after reading TCFV = 1
R/(W)* Input Capture/Output Compare Flag D
Status flag that indicates the occurrence of TGRD input
capture or compare match in channel 0. In channels 1 and
2, bit 3 is reserved. It is always read as 0 and cannot be
modified.
[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
[Clearing condition]
•
When 0 is written to TGFD after reading TGFD = 1
R/(W)* Input Capture/Output Compare Flag C
Status flag that indicates the occurrence of TGRC input
capture or compare match in channel 0. In channels 1 and
2, bit 2 is reserved. It is always read as 0 and cannot be
modified.
[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
[Clearing condition]
•
When 0 is written to TGFC after reading TGFC = 1
