bit 7 bit 0
Legend:
R = Readable bit W = Writable bit U = Unimplemented bit, read as ‘0’
-n = Value at POR ‘1’ = Bit is set ‘0’ = Bit is cleared x = Bit is unknown
bit 15 SEVTDIR: Special Event Trigger Time Base Direction bit
(1)
1 = A Special Event Trigger will occur when the PWM time base is counting downward
0 = A Special Event Trigger will occur when the PWM time base is counting upward
bit 14-0 SEVTCMP<14:0>: Special Event Compare Value bits
(2)
Note 1: SEVTDIR is compared with PTDIR (PXTMR<15>) to generate the Special Event Trigger.
2: PxSECMP<14:0> is compared with P
XTMR<14:0> to generate the Special Event Trigger.
