is "1", the PWM0 pin changes from the "L" to "H" level. If the 2 × n-th overflow occurs at this time, an
INTTC00 interrupt request is generated. (No interrupt request is generated at the 2 × n-th -1 overflow.)
Subsequently, the up counter continues counting up.
to "0x00". The PWM0 pin returns to the level selected at T00MOD<TFF0>.
(Example) Operate TC00 in the 8-bit PWM mode with the operation clock of fcgck/2 and output a duty pulse nearly
When T001CR<T00RUN> is set to "0" during the timer operation, the up counter is stopped and cleared
