NMRA CV 9 - Total PWM Period
THIS FEATURE IS NOT (YET) SUPPORTED BY THE WOWDIESEL V5
The value of CV#9 sets the nominal PWM period at the decoder output and therefore the frequency is proportional to the reciprocal of the value.
The recommend formula for PWM period should be:
PWM period (uS) = (131 + MANTISSA x 4)x 2 EXP
Where MANTISSA is in bits 0-4 bits of CV#9 (low order) and EXP is bits 5-7 for CV#9. If the value programmed into CV-9 falls outside a decoder's capability, it is suggested (but not required) that the decoder "adjust" the value to the appropriate highest or lowest setting supported by the decoder
