Tiva^™ TM4C1299NCZAD Microcontroller
Register 84: PWM0 Fault Status 1 (PWM0FLTSTAT1), offset 0x808
Register 85: PWM1 Fault Status 1 (PWM1FLTSTAT1), offset 0x888
Register 86: PWM2 Fault Status 1 (PWM2FLTSTAT1), offset 0x908
Register 87: PWM3 Fault Status 1 (PWM3FLTSTAT1), offset 0x988
Along with the PWMnFLTSTAT0 register, this register provides status regarding the fault condition
inputs.
If the LATCH bit in the PWMnCTL register is clear, the contents of the PWMnFLTSTAT1 register
are read-only (RO) and provide the current state of the digital comparator triggers.
If the LATCH bit in the PWMnCTL register is set, the contents of the PWMnFLTSTAT1 register are
read / write 1 to clear (RW1C) and provide a latched version of the digital comparator triggers. In
this mode, the register bits are cleared by writing a 1 to a set bit. 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).
Note: The fault status registers, PWMnFLTSTAT0 and PWMnFLTSTAT1, reflect the status of all
fault sources, regardless of what fault sources are enabled for that particular generator.

Reset Description
0x0000.00 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.

Digital Comparator 7 Trigger
If the PWMnCTL register LATCH bit is clear, this bit represents the
current state of the Digital Comparator 7 trigger input.
If the PWMnCTL register LATCH bit is set, this bit represents a sticky
version of the trigger.
■ If DCMP7 is set, the trigger transitioned to the active state previously.
■ If DCMP7 is clear, the trigger has not transitioned to the active state
since the last time it was cleared.
■ The DCMP7 bit is cleared by writing it with the value 1.
