Fault Mode Selection for Fault Pin 3 Bit
(automatic versus manual mode)
This read/write bit allows the user to select between automatic and
manual mode faults. For further descriptions of each mode,
see
9.7 Fault Protection
.
1 = Automatic mode
0 = Manual mode
FINT2
—
Fault 2 Interrupt Enable Bit
This read/write bit allows the CPU interrupt caused by faults on fault
pin 2 to be enabled. The fault protection circuitry is independent of this
bit and will always be active. If a fault is detected, the PWM pins will
still be disabled according to the disable mapping register.
1 = Fault pin 2 will cause CPU interrupts.
0 = Fault pin 2 will not cause CPU interrupts.

Fault 1 Interrupt Enable Bit
This read/write bit allows the CPU interrupt caused by faults on fault
pin 1 to be enabled. The fault protection circuitry is independent of this
bit and will always be active. If a fault is detected, the PWM pins will
still be disabled according to the disable mapping register.
1 = Fault pin 1 will cause CPU interrupts.
0 = Fault pin 1 will not cause CPU interrupts.
