bit 7 bit 0
Legend: HSC = Hardware Settable/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 12-10 OCTSEL<2:0>: Output Compare x Clock Select bits
111 = Peripheral clock (F
P)
110 = Reserved
101 = PTGOx clock
(2)
100 = T1CLK is the clock source of the OCx (only the synchronous clock is supported)
011 = T5CLK is the clock source of the OCx
010 = T4CLK is the clock source of the OCx
001 = T3CLK is the clock source of the OCx
000 = T2CLK is the clock source of the OCx
bit 9 Unimplemented: Read as ‘0’
bit 8 ENFLTB: Fault B Input Enable bit
1 = Output Compare Fault B input (OCFB) is enabled
0 = Output Compare Fault B input (OCFB) is disabled
bit 7 ENFLTA: Fault A Input Enable bit
1 = Output Compare Fault A input (OCFA) is enabled
0 = Output Compare Fault A input (OCFA) is disabled
bit 6 Unimplemented: Read as ‘0’
bit 5 OCFLTB: PWM Fault B Condition Status bit
1 = PWM Fault B condition on OCFB pin has occurred
0 = No PWM Fault B condition on OCFB pin has occurred
bit 4 OCFLTA: PWM Fault A Condition Status bit
1 = PWM Fault A condition on OCFA pin has occurred
0 = No PWM Fault A condition on OCFA pin has occurred
Note 1: OCxR and OCxRS are double-buffered in PWM mode only.
2: Each Output Compare x module (OCx) has one PTG clock source. See Section 24.0 “Peripheral Trigger
Generator (PTG) Module” for more information.
PTGO4 = OC1
PTGO5 = OC2
PTGO6 = OC3
PTGO7 = OC4
