Stellaris^® LM3S5G56 Microcontroller
Register 64: PWM0 Fault Status 0 (PWM0FLTSTAT0), offset 0x804
Register 65: PWM1 Fault Status 0 (PWM1FLTSTAT0), offset 0x884
Register 66: PWM2 Fault Status 0 (PWM2FLTSTAT0), offset 0x904
Along with the PWMnFLTSTAT1 register, this register provides status regarding the fault condition
inputs.
If the LATCH bit in the PWMnCTL register is clear, the contents of the PWMnFLTSTAT0 register
are read-only (RO) and provide the current state of the FAULTn inputs.
If the LATCH bit in the PWMnCTL register is set, the contents of the PWMnFLTSTAT0 register are
read / write 1 to clear (R/W1C) and provide a latched version of the FAULTn inputs. In this mode,
the register bits are cleared by writing a 1 to a set bit. The FAULTn inputs are recorded after their
sense is adjusted in the generator.
The contents of this register can only be written if the fault source extensions are enabled (the
FLTSRC bit in the PWMnCTL register is set).

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.
Fault Input 3
If the PWMnCTL register LATCH bit is clear, this bit is RO and represents
the current state of the FAULT3 input signal after the logic sense
adjustment.
If the PWMnCTL register LATCH bit is set, this bit is R/W1C and
represents a sticky version of the FAULT3 input signal after the logic
sense adjustment.
■ If FAULT3 is set, the input transitioned to the active state previously.
■ If FAULT3 is clear, the input has not transitioned to the active state
since the last time it was cleared.
■ The FAULT3 bit is cleared by writing it with the value 1.
