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.
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
for more information.
