S12 Output COmpare

[Greeny]

Hey,

i have a problem with the Output Compare function of my MC9S12C64 µC.

When i set the bit for Channel 6 Output Compare in the TIOS register i get the error Illegal_BP when starting the code.

if i use the bean wizard in codewarrior i can generate a pulse but it has double the length i set. If i set pulse width 2730µs then i will measure 5,4µs.

need help plzz

This kind of issues is often caused a incorrect value in "Clock frequency [MHz]" available after unfolding "Input clock" and "Clock setting groups" in CPU bean. Could you please check that the value in the "Clock frequency [MHz]" corresponds to the value of crystal (oscillator) on your PCB board?

What bean are you using? This information is not mentioned in your post.
