KV4x - NanoEdge - FRACVAL1 PWM period problem

I am Davide Lusignani, from University of Parma (Italy).

I need to use NanoEdge function on KV4x device (MKV46F256VLL16) on all 12 PWM outputs.

The PWM period of PWMA and PWMB outputs changes when I modify FRACVAL1 register to control the duty-cycle of PWMX.

How can I disable this function and use FRACVAL1 without modifing the PWM frequency?

ps: the period of the PWM is set by EXT_SYNC from a timer.

Thanks in advance
