PWM_TIMER0_PERIOD_UPMETHOD Updating method for active register of PWM timer0 period. 0:
immediately, 1: update at TEZ, 2: update at sync, 3: update at TEZ or sync. TEZ here and below
means that the event that happens when the timer equals to zero. (R/W)
PWM_TIMER0_PERIOD Period shadow register of PWM timer0. (R/W)
PWM_TIMER0_PRESCALE Period of PT0_clk = Period of PWM_clk * (PWM_TIMER0_PRESCALE +
1). (R/W)
