14.12.2
The FLTAMOD bit in the FLTCONFIG register
determines whether the PWM I/O pins are deactivated
when they are overridden by a Fault input.
FLTAS bit in the FLTCONFIG register gives the status
of the Fault A input.
The Fault input has two modes of operation:
• Inactive Mode (FLTAMOD = 0)
• Cycle-by-Cycle Mode (FLTAMOD = 1)

This is a catastrophic Fault Management mode.
When the Fault occurs in this mode, the PWM
outputs are deactivated. The PWM pins will remain in
Inactivated mode until the Fault is cleared (Fault
input is driven high) and the corresponding Fault
status bit has been cleared in software. The PWM
outputs are enabled immediately at the beginning of
the following PWM period, after Fault status bit
(FLTAS) is cleared.
When the Fault occurs in this mode, the PWM
outputs are deactivated. The PWM outputs will
remain in the defined Fault states (all PWM outputs
inactive) for as long as the Fault pin is held low. After
the Fault pin is driven high, the PWM outputs will
return to normal operation at the beginning of the
following PWM period and the FLTAS bit is
automatically cleared.

14.12.3
While in the Fault state (i.e., FLTA input is active), the
PWM output signals are driven into their inactive
states.
14.12.4
The BRFEN bit in the FLTCONFIG register controls the
simulation of Fault condition when a breakpoint is hit,
while debugging the application using an In-Circuit
Debugger (ICD). Setting the BRFEN bit to high enables
the Fault condition on breakpoint, thus driving the PWM
outputs to inactive state. This is done to avoid any
continuous keeping of status on the PWM pin, which
may result in damage of the power devices connected
to the PWM outputs.
If BRFEN = 0, the Fault condition on breakpoint is
disabled.
