Scaled clock S is generated by dividing clock A by the value in PWSCAL, then dividing the result by 2.
If PWSCAL = $00, divide clock A by 256, then divide the result by 2.

Always read zero
Begins count using whichever clock was selected
0 = Clock B is source
1 = Clock S is source
0 = Clock A is source
1 = Clock S is source
0 = Clock A is source
1 = Clock S is source
0 = PWM channel x output is low at the beginning of the clock cycle and goes high when duty count
1 = PWM channel x output is high at the beginning of the clock cycle and goes low when duty count
0 = Channel disabled
1 = Channel enabled
