PWM using TPM low level voltage

Hello there,

 

I'm using the TPM1CH3 of the S08EL32 to generate a PWM. The PWM is there the the low level votlage is 400mV and the high level voltage is 3V with 3.3V power supply whereas if I turn this pin into an I/O, then low level voltage is 40mV and high level voltage is close to 3.3V.

 

This makes me in trouble in order to drive a FET from the PWM output.

 

Is it a normal feature ?

Stephane
