Chapter 8 Pulse-Width Modulator (S12PWM8B8CV1)
Read: Anytime
Write: Anytime (causes the scale counter to load the PWMSCLA value)
8.3.2.10
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).
8.3.2.11
The registers PWMSCNTA and PWMSCNTB are reserved for factory testing of the PWM module and are
not available in normal modes.
Read: Always read $00 in normal modes
Write: Unimplemented in normal modes

When PWMSCLB = $00, PWMSCLB value is considered a full scale value
of 256. Clock B is thus divided by 512.
