bit 7

bit 0

Legend:

HC = Hardware Clearable 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 15-14

Unimplemented:

Read as ‘0’

bit 13

OCSIDL:

Stop Output Compare 1 in Idle Mode Control bit

= Output Compare 1 will halt in CPU Idle mode

= Output Compare 1 will continue to operate in CPU Idle mode

bit 12-5

Unimplemented:

Read as ‘0’

bit 4

OCFLT:

PWM Fault Condition Status bit

= PWM Fault condition has occurred (cleared in HW only)

= No PWM Fault condition has occurred (this bit is only used when OCM<2:0> = 111)

bit 3

OCTSEL:

Output Compare 1 Timer Select bit

= Timer3 is the clock source for Output Compare 1

= Timer2 is the clock source for Output Compare 1

Refer to the device data sheet for specific time bases available to the output compare module.

bit 2-0

OCM<2:0>:

Output Compare 1 Mode Select bits

111

= PWM mode on OC1, Fault pin; OFCA enabled(1)

110

= PWM mode on OC1, Fault pin; OFCA disabled(1)

101

= Initialize OC1 pin low, generate continuous output pulses on OC1 pin

100

= Initialize OC1 pin low, generate single output pulse on OC1 pin

011

= Compare event toggles OC1 pin

010

= Initialize OC1 pin high, compare event forces OC1 pin low

001

= Initialize OC1 pin low, compare event forces OC1 pin high

000

= Output compare channel is disabled

Note 1:

OCFA pin controls OC1 channel.
