(TC1DRA and TC1DRB).
The TimerCounter 1 is controlled by the TimerCounter 1 control register (TC1CR) and two 16-bit timer registers
Note 1: fc: High-frequency clock [Hz]
Note 2: The timer register consists of two shift registers. A value set in the timer register becomes valid at the rising edge of the
Note 3: To set the mode, source clock, PPG output control and timer F/F control, write to TC1CR during TC1CR<TC1S>=00. Set
Note 4: Auto-capture can be used only in the timer, event counter, and window modes.
