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 OCFLTA bit is

cleared in software and a new PWMx period starts

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

bit 14

FLTOUT: Fault Out bit

1 = PWMx output is driven high on a Fault

0 = PWMx 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 = OCx module drives the OCx pin

Note 1:

Do not use the OCx module as its own synchronization or trigger source.

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.

For each OCMPx instance, a different PTG trigger out is used:

OCMP1 – PTG trigger out [0]

OCMP2 – PTG trigger out [1]

OCMP3 – PTG trigger out [2]

OCMP4 – PTG trigger out [3]
