Pulse-Width Modulator (PWM8B6CV1) Block Description
Read: anytime
Write: anytime (causes the scale counter to load the PWMSCLA value)
10.3.2.10 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).
10.3.2.11 Reserved Registers (PWMSCNTx)
The registers PWMSCNTA and PWMSCNTB are reserved for factory testing of the PWM module and
are not available in normal modes.

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