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
1
= Output Compare 1 will halt in CPU Idle mode
0
= 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
1
= PWM Fault condition has occurred (cleared in HW only)
0
= 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
1
= Timer3 is the clock source for Output Compare 1
0
= 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; OCF1 enabled
(
)
110
= PWM mode on OC1, Fault pin; OCF1 disabled
)
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:
The OCFA pin controls the OC1 channel.
