I am developing an application code on a MC9S12ZVL microcontroller.
I have a problem using the PWM2 output signal connested to PT0 port.
The PWM2 output works properly when I download the code on the micro and I keep the Multilink programmer connected (I use that PWM suìignal to drive a LED changing the light intensity and everything works in the right way). If I disconnect the multilink, switch off and then on again the micro, no PWM signal goes out from the PT0 port (PWM2 output does not work).
I use other PWM signal to drive other LEDs and they still work properly even if the programmer is not connected and the code starts from flash.
For the application I made a patch on the board using an other PWM (I used PWM7 instead of PWM2) but I would like to understand the problem for the future.
I guess the key point could be in the initialization procedure that the multilink programmer makes when connected.
Could you help me in fixing this problem?
Thanks in advance
