TMS320F28075: about PWM frequency

Part Number: TMS320F28075


Hello everyone:


My project uses 28075 for master, The  PWM frequency has been configured at 120MHz, and temporarily did not find any problems!

Now I see the 28075 Datesheet on the description, PWM frequency can only be 100MHz. When the frequency is 120Mhz, pwm frequency intelligent configuration to 60MHz.

My question is:

1, why pwm frequency can not be configured to more than 100MHz?

2, if the PWM frequency configuration at 120MHz, what will be the consequences or what effect?
