PWM_TIMER0_MOD PWM timer0 working mode. 0: freeze, 1: increase mode, 2: decrease mode,
3: up-down mode. (R/W)
PWM_TIMER0_START PWM timer0 start and stop control. 0: if PWM timer0 starts, then stops at
TEZ; 1: if timer0 starts, then stops at TEP; 2: PWM timer0 starts and runs on; 3: timer0 starts and
stops at the next TEZ; 4: timer0 starts and stops at the next TEP. TEP here and below means
the event that happens when the timer equals to period. (R/W)

PWM_TIMER0_PHASE_DIRECTION 0: increase; 1: decrease. (R/W)
PWM_TIMER0_PHASE Phase for timer reload at sync event. (R/W)
PWM_TIMER1_SYNCO_SEL PWM timer0 sync_out selection. 0: sync_in; 1: TEZ; 2: TEP; otherwise:
sync_out is always 0. (R/W)
PWM_TIMER1_SYNC_SW Toggling this bit will trigger a software sync. (R/W)
PWM_TIMER1_SYNCI_EN When set, timer reloading with phase on sync input event is enabled.
