(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
(c) Overflow 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.
The 16-bit counter overflows when it counts up from FFFFH to 0000H in the free-running mode, pulse
width measurement mode, and encoder compare mode. If the counter overflows in the free-running mode
and pulse width measurement mode, the TT0OPT0.TT0OVF bit is set to 1 and an interrupt request signal
(INTTT0OV) is generated.
If the counter overflows in the encoder compare mode, the TT0OPT1.TT0EOF bit is set to 1 and an
interrupt request signal (INTTT0OV) is generated.
Note that the INTTT0OV signal is not generated under the following conditions.
• Immediately after a count operation has been started
• If the counter value matches the compare value FFFFH and is cleared
• When FFFFH is captured and cleared to 0000H in the pulse width measurement mode
Caution After the overflow interrupt request signal (INTTT0OV) has been generated, be sure to
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.
check that the overflow flag (TT0OVF, TT0EOF bits) is set to 1.
