Polarity control bits, HPOL and LPOL, define PWM signal output active and inactive states, PWM states
generated by the Fault inputs or PWM manual override.
When PWMPIN = 0, PWMEN<2:0> = 100. PWM output polarity is defined by HPOL and LPOL.
Unimplemented: Read as ‘0’
HPOL: High Side Transistors Polarity bit (Odd PWM Output Polarity Control bit)
1 = PWM1, PWM3 and PWM5 are active-high (default)
0 = PWM1, PWM3 and PWM5 are active-low
LPOL: Low Side Transistors Polarity bit (Even PWM Output Polarity Control bit)
1 = PWM0, PWM2 and PWM4 are active-high (default)
0 = PWM0, PWM2 and PWM4 are active-low
PWMPIN: PWM Output Pins Reset State Control bit
1 = PWM outputs disabled upon Reset
0 = PWM outputs drive active states upon Reset
Unimplemented: Read as ‘0’
