HEllo,

in the KLQRUG app note this frequency this formula is given:

so for CenterPWM the TPMPerio=  (MOD x Tmie Step) / 2

However this does not make sense to me. From the datasheet:

so I would think for CPWM T=  (MOD x time Step) x 2

Can you confirm if there is an error in the appnote?

Thanks!
