POVD
PWM Override Data represents the value of PWM[7:0] respectively in override
mode.
1 = Output on PWM I/O pin is ACTIVE when the corresponding PWM output
override bit is cleared.
0 = Output on PWM I/O pin is INACTIVE when the corresponding PWM output
override bit is cleared.

PIO.x
Select pin output source from PWM or I/O register; x=0~7; PIOn is effective only
when option bit PWMOE/PWMEE/PWM6E/PWM7E is in enabled status. Reset
value=0;
1 = Correspondent I/O pin with high source/sink current.
0 = PWMn output; n=0~7 with high source/sink current.
