PWM_TIMER1_MOD PWM timer1 working mode. 0: freeze, 1: increase mode, 2: decrease mode,
3: up-down mode. (R/W)
PWM_TIMER1_START PWM timer1 start and stop control. 0: if PWM timer1 starts, then stops at TEZ;
1: if PWM timer1 starts, then stops at TEP; 2: PWM timer1 starts and runs on; 3: PWM timer1 starts
and stops at the next TEZ; 4: PWM timer1 starts and stops at the next TEP. (R/W)

PWM_TIMER1_PHASE_DIRECTION 0: increase; 1: decrease. (R/W)
PWM_TIMER1_PHASE Phase for timer reload at sync event. (R/W)
PWM_TIMER1_SYNCO_SEL PWM timer1 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 at a sync input event is enabled.
