(1) Basic counter operation
This section explains the basic operation of the 16-bit counter. For details, refer to the description of the operation
in each mode.
(a) Count start operation
(b) Clear operation
• Encoder compare mode
• Triangular-wave PWM mode
• Mode other than above
The 16-bit counter is cleared to 0000H when its value matches the value of the compare register, when its
value is captured, when the edge of the encoder clear signal is detected, and when the clear level condition of
the TENC00, TENC01, and TECR0 pins is detected. The count operation from FFFFH to 0000H that takes
place immediately after the counter has started counting or when the counter overflows is not a clear operation.
Therefore, the INTTT0CC0 and INTTT0CC1 interrupt signals are not generated.
A count operation is controlled by TENC00 and TENC01 phases.
The 16-bit counter initial setting is performed by transferring the set value of the TT0TCW register to the 16-
bit counter and the count operation is started. (When the TT0CTL2.TT0ECC bit = 0, the TT0TCW register set
value is transferred to the 16-bit counter at the timing when the TT0CTL0.TT0CE bit changes from 0 to 1.)
The 16-bit counter starts counting from the initial value FFFFH.
It counts up FFFFH, 0000H, 0001H, 0002H, 0003H, and so on.
Following the count-up operation, the counter counts down upon a match between the 16-bit count value and
the CCR0 buffer register.
The 16-bit counter starts counting from the initial value FFFFH.
It counts up FFFFH, 0000H, 0001H, 0002H, 0003H, and so on.
