Timer Rn has two counters, a counter and a sub-counter.
TRnCUF is the counter’s up/down status flag. It operates in the triangular wave PWM mode and high-
accuracy T-PWM mode, and is fixed to 0 in all other modes.
TRnSUF is the sub-counter’s up/down status flag. It operates in the high-accuracy T-PWM mode, and is
fixed to 0 in all other modes.
For both TRnCUF and TRnSUF, 0 indicates the up count status, and 1 indicates the down count status.

Up Count Flags Timings (1/2)
In the triangular wave PWM mode, the values of TRnCUF are as follows.
0
≤
counter < 1
…
0 (up count)
1
≥
counter > 0
…
1 (down count)
In the high-accuracy T-PWM mode, the values of TRnCUF/TRnSUF are as follows.
[TRnCUF]
TRnDTC0
≤
counter < (TRnCCR0 - TRnDTC1)
…
0 (up count)
TRnCCR0-TRnDTC1
≥
counter > TRnDTC0
…
1 (down count)
[TRnSUF]
0
≤
sub-counter < TRnCCR0
…
0 (up count)
TRnCCR0
≥
sub-counter > 0
…
1 (down count)
