These bits are always read as 1. The write value
should always be 1.
5 to 2 —

These bits are always read as 0. The write value
should always be 0.

R/(W)*¹ Compare Match Flag F
Status flag that indicates the occurrence of compare
match between TCNT_0 and TGRF_0.
[Setting condition]
• When TCNT_0 = TGRF_0 and TGRF_0 is
functioning as compare register
[Clearing condition]
0
TGFE
0
• When 0 is written to TGFF after reading TGFF =
1*²
R/(W)*¹ Compare Match Flag E
Status flag that indicates the occurrence of compare
match between TCNT_0 and TGRE_0.
[Setting condition]
• When TCNT_0 = TGRE_0 and TGRE_0 is
functioning as compare register
[Clearing condition]
• When 0 is written to TGFE after reading TGFE =
1*²
Notes: 1. Writing 0 to this bit after reading it as 1 clears the flag and is the only allowed way.
2. If another flag setting condition occurs before writing 0 to the bit after reading it as 1, the
flag will not be cleared by writing 0 to it once. In this case, read the bit as 1 again and
write 0 to it.
