The TimerCounter 4 is controlled by the TimerCounter 4 control register (TC4CR) and two 8-bit timer regis-
Note 1: Do not change the timer register (TTREG4) setting while the timer is running.
Note 2: Do not change the timer register (PWREG4) 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 TC4M, TC4CK and TFF4 settings while the timer is running.
Note 3: To stop the timer operation (TC4S= 1 → 0), do not change the TC4M, TC4CK and TFF4 settings.
Note 4: When TC4M= 1** (upper byte in the 16-bit mode), the source clock becomes the TC3 overflow signal regardless of
