Chapter 12 Pulse-Width Modulator (PWM8B6CV1) Block Description
12.3.2.9
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).
Read: anytime
Write: anytime (causes the scale counter to load the PWMSCLA value)
12.3.2.10 PWM Scale B Register (PWMSCLB)
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).
Read: anytime
Write: anytime (causes the scale counter to load the PWMSCLB value).

When PWMSCLA = 0x0000, PWMSCLA value is considered a full scale
value of 256. Clock A is thus divided by 512.
When PWMSCLB = 0x0000, PWMSCLB value is considered a full scale
value of 256. Clock B is thus divided by 512.
