8-bit pulse width modulation (PWM) output modes. The TimerCounter 3 and 4 (TC3, 4) 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, warm-up coun-
ter, 16-bit pulse width modulation (PWM) output and 16-bit programmable pulse generation (PPG) modes.

Function
The TimerCounter 3 and 4 have the 8-bit timer, 8-bit event counter, 8-bit programmable divider output (PDO),
NORMAL1/2, IDLE1/2 mode
Note:In the timer mode, do not select a source clock other than those shown above.

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

In the timer mode, the up-counter counts up using the internal clock. When a match between the up-coun-

the shift register configuration in the timer mode, the new value programmed in TTREGj is in effect imme-
diately after the programming. Therefore, if TTREGj is changed while the timer is running, an expected op-
eration may not be obtained.
