Enhanced Motor Control Timer (eTimer)
INPUT - External input signal
This read only bit reflects the current state of the signal selected via SECSRC after application of the
SIPS bit and filtering.
VAL - Forced OFLAG Value
This bit determines the value of the OFLAG output signal when a software triggered FORCE
command occurs.
FORCE- Force the OFLAG output
This write only bit forces the current value of the VAL bit to be written to the OFLAG output. This bit
always reads as a zero. The VAL and FORCE bits can be written simultaneously in a single write
operation. Write to the FORCE bit only if OUTMODE is 0000 (software controlled). Setting this bit
while the OUTMODE is a different value may yield unpredictable results.
COFRC - Co-channel OFLAG Force
This bit enables the compare from another channel within the module to force the state of this counter’s
OFLAG output signal.
1 = Other channels may force the OFLAG of this channel.
0 = Other channels cannot force the OFLAG of this channel.
COINIT - Co-channel Initialization
These bits enable another channel within the module to force the re-initialization of this channel when
the other channel has an active compare event.

Meaning
Other channels cnnot force re-initialization of this channel.
Other channels may force a re-initialization of this channel’s counter using the LOAD reg.
Other channels may force a re-initialization of this channel’s counter with the CMPLD2
reg when this channel is counting down or the CMPLD1 reg when this channel is counting
up.
Reserved.
SIPS - Secondary Source Input Polarity Select
This bit inverts the polarity of the signal selected by the SECSRC bits.
1 = Inverted polarity.
0 = True polarity.
PIPS - Primary Source Input Polarity Select
This bit inverts the polarity of the signal selected by the PRISRC bits. This only applies if the signal
selected by PRISRC is not the prescaled IP Bus clock.
1 = Inverted polarity.
0 = True polarity.
OPS - Output Polarity Select.
