TimerCounter Control
The TimerCounter 3 is controlled by the TimerCounter 3 control register (TC3CR) and two 8-bit timer regis-
Note 1: Do not change the timer register (TTREG3) setting while the timer is running.
Note 2: Do not change the timer register (PWREG3) setting in the operating mode except the 8-bit and 16-bit PWM modes
Note 1: fc: High-frequency clock [Hz] fs: Low-frequency clock[Hz]
Note 2: Do not change the TC3M, TC3CK and TFF3 settings while the timer is running.
Note 3: To stop the timer operation (TC3S= 1 → 0), do not change the TC3M, TC3CK and TFF3 settings. To start the timer op-
Note 4: To use the TimerCounter in the 16-bit mode, set the operating mode by programming TC4CR<TC4M>, where TC3M
