OCTRIG TRIGSTAT OCTRIS SYNCSEL<4:0>

bit 7 bit 0

Legend: HS = Hardware Settable bit

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 FLTMD: Fault Mode Select bit

1 = Fault mode is maintained until the Fault source is removed; the corresponding OCFLTx bit is

cleared in software and a new PWM period starts

0 = Fault mode is maintained until the Fault source is removed and a new PWM period starts

bit 14 FLTOUT: Fault Out bit

1 = PWM output is driven high on a Fault

0 = PWM output is driven low on a Fault

bit 13 FLTTRIEN: Fault Output State Select bit

1 = OCx pin is tri-stated on a Fault condition

0 = OCx pin I/O state is defined by the FLTOUT bit on a Fault condition

bit 12 OCINV: Output Compare x Invert bit

1 = OCx output is inverted

0 = OCx output is not inverted

bit 11-9 Unimplemented: Read as ‘0’

bit 8 OC32: Cascade Two OCx Modules Enable bit (32-bit operation)

1 = Cascade module operation is enabled

0 = Cascade module operation is disabled

bit 7 OCTRIG: Output Compare x Trigger/Sync Select bit

1 = Triggers OCx from the source designated by the SYNCSELx bits

0 = Synchronizes OCx with the source designated by the SYNCSELx bits

bit 6 TRIGSTAT: Timer Trigger Status bit

1 = Timer source has been triggered and is running

0 = Timer source has not been triggered and is being held clear

bit 5 OCTRIS: Output Compare x Output Pin Direction Select bit

1 = OCx is tri-stated

0 = Output Compare x module drives the OCx pin

Note 1: Do not use the OCx module as its own Synchronization or Trigger source.

2: When the OCy module is turned OFF, it sends a trigger out signal. If the OCx module uses the OCy

module as a Trigger source, the OCy module must be unselected as a Trigger source prior to disabling it.

3: Each Output Compare x module (OCx) has one PTG Trigger/Synchronization source. See Section 24.0

“Peripheral Trigger Generator (PTG) Module” for more information.

PTGO0 = OC1

PTGO1 = OC2

PTGO2 = OC3

PTGO3 = OC4
