Enable use of trigger on PWM_n.
S/W writes ‘1’ to reset counter in WDT mode
Writing ‘1 and PWM/One
0: low-to-high
1: hi-to-low
0: one-shot timer mode
1: watch-dog timer mode
This bit is only valid if the ALT bits in the Channel_function_En register is set to ‘1’
For one-shot mode only .
Reload bit defines whether reload is necessary after trigger has occured
0: to disable Auto-Reload
1: to enable Auto-Reload
