bit pulse width modulation (PWM) output modes. The TimerCounter 5 and 6 (TC5, 6) are cascadable to form a 16-
bit timer. The 16-bit timer has the operating modes such as the 16-bit timer, 16-bit event counter, 16-bit pulse width
modulation (PWM) output and 16-bit programmable pulse generation (PPG) modes.
The TimerCounter 5 and 6 have the 8-bit timer, 8-bit event counter, 8-bit programmable divider output (PDO), 8-

and the timer register j (TTREGj) value is detected, an INTTCj interrupt is generated and the up-counter is cleared.
After being cleared, the up-counter restarts counting.
Note 1: In the timer mode, fix TCjCR<TFFj> to 0. If not fixed, the PDOj, PWMj and PPGj pins may output pulses.
Note 2: In the timer mode, do not change the TTREGj setting while the timer is running. Since TTREGj is not in the
Note 3: j = 5, 6
In the timer mode, the up-counter counts up using the internal clock. When a match between the up-counter

shift register configuration in the timer mode, the new value programmed in TTREGj is in effect immediately
after the programming. Therefore, if TTREGi is changed while the timer is running, an expected operation
may not be obtained.
