Note:
Functional Description and Application Information
4.13.3.3
PWMSCLA is the programmable scale value used in scaling clock A to generate clock SA. Clock SA is generated by taking clock
A, dividing it by the value in the PWMSCLA register and dividing that by two.
Any value written to this register will cause the scale counter to load the new scale value (PWMSCLA)
4.13.3.4
PWMSCLB is the programmable scale value used in scaling clock B to generate clock SB. Clock SB is generated by taking clock
B, dividing it by the value in the PWMSCLB register and dividing that by two.
Any value written to this register will cause the scale counter to load the new scale value (PWMSCLB).

When PWMSCLA = $00, PWMSCLA value is considered a full scale value of 256. Clock A
is thus divided by 512.
Clock SA = Clock A / (2 * PWMSCLA)
When PWMSCLB = $00, PWMSCLB value is considered a full scale value of 256. Clock B
is thus divided by 512.
Clock SB = Clock B / (2 * PWMSCLB)
