Read: Always read $00 in normal modes
Write: Unimplemented in normal modes
NOTE
Writing to this register when in special modes can alter the PWM
functionality.

12.3.2.9 PWM Scale A Register (PWMSCLA)
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.
Clock SA = Clock A / (2 * PWMSCLA)
