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: Output Compare x Stop in Idle Mode Control bit
1 = Output Compare x halts in CPU Idle mode
0 = Output Compare x continues 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 x Timer Select bit
1 = Timer3 is the clock source for Output Compare x
0 = Timer2 is the clock source for Output Compare x
Refer to the device data sheet for specific time bases available to the output compare module.
bit 2-0 OCM<2:0>: Output Compare x Mode Select bits
(1)
111 = PWM mode on OCx; Fault pin, OCFx, is enabled
(2)
110 = PWM mode on OCx; Fault pin, OCFx, is disabled
(2)
101 = Initializes OCx pin low, generates continuous output pulses on OCx pin
100 = Initializes OCx pin low, generates single output pulse on OCx pin
011 = Compare event toggles OCx pin
010 = Initializes OCx pin high, compare event forces OCx pin low
001 = Initializes OCx pin low, compare event forces OCx pin high
000 = Output compare channel is disabled
Note 1: RPORx (OCx) must be configured to an available RPn pin. For more information, see Section 10.4
“Peripheral Pin Select (PPS)”.
2: The OCFA pin controls the OC1-OC4 channels. The OCFB pin controls the OC5 channel.
