(0x002A)
Note 1: fcgck: Gear clock [Hz], fs: Low-frequency clock [Hz]
Note 2: Set T00MOD while the timer is stopped. Writing data into T00MOD is invalid during the timer operation.
Note 3: In the 8-bit timer/event modes, the TFF0 setting is invalid. In this mode, when the PWM0 and PPG0 pins are set as the
Note 4: When EIN0 is set to "1" and the external clock input is selected as the source clock, the TCK0 setting is ignored.
Note 5: When the T001CR<TCAS> bit is "1", timer 00 operates in the 16-bit mode. The T00MOD setting is invalid and timer 00
Note 6: When the 16-bit mode is selected at T001CR<TCAS>, the timer start is controlled at T001CR<T01RUN>. Timer 00 is not
