Pulse Width Modulator (PWM)
Register 63: PWM0 Fault Source 0 (PWM0FLTSRC0), offset 0x074
Register 64: PWM1 Fault Source 0 (PWM1FLTSRC0), offset 0x0B4
Register 65: PWM2 Fault Source 0 (PWM2FLTSRC0), offset 0x0F4
Register 66: PWM3 Fault Source 0 (PWM3FLTSRC0), offset 0x134
This register specifies which fault pin inputs are used to indicate a fault condition. Each bit in the
following register indicates whether the corresponding fault pin is included in the fault condition. All
enabled fault pins are ORed together to form the PWMnFLTSRC0 portion of the fault condition.
The PWMnFLTSRC0 fault condition is then ORed with the PWMnFLTSRC1 fault condition to
generate the final fault condition for the PWM generator.
If the FLTSRC bit in the PWMnCTL register (see page 633) is clear, only the PWM Fault0 pin affects
the fault condition generated. Otherwise, sources defined in PWMnFLTSRC0 and PWMnFLTSRC1
affect the fault condition generated.

Description
Software should not rely on the value of a reserved bit. To provide
compatibility with future products, the value of a reserved bit should be
preserved across a read-modify-write operation.
Fault2
The same function as Fault0, except applied for the FAULT2 input.
Note: The FLTSRC bit in the PWMnCTL register must be set for this
bit to affect fault condition generation.
Fault1
The same function as Fault0, except applied for the FAULT1 input.
Note: The FLTSRC bit in the PWMnCTL register must be set for this
bit to affect fault condition generation.
