FB pin input enable
0 = PWM output Fault Braked by FB pin input Disabled.
1 = PWM output Fault Braked by FB pin input Enabled. Once an edge, which matches
FBINLS (PWM0FBD.6) selection, occurs on FB pin, PWM0 channel 0~5 output Fault
Brake data in PWM0FBD register and PWM6/7 remains their states. PWM0RUN
(PWM0CON0.7) will also be automatically cleared by hardware. The PWM output
resumes when PWM0RUN is set again.
