I am using the MC9S08AC16 micro
The program I am working on makes the uP go to sleep (Stop3) about 20 seconds after power up, then it gets awaken by IRQ.
All outputs I am using then seem to change into inputs until all the registers are configured properly.
This is a problem because this means outputs are floating for about 2ms.
I have been using the CodeWarrior debugger, and I could see that pin E1 would be an input right after wake up/power up and set properly as an output only after this code:
for( x = 0; x <= 13; x++ ) /* load registers 0 to 13 */
*((near byte *) x) = register_setup[x];
I would like the uP to keep the same data direction after wake up as before (Note that the I/O direction is kept OK during sleep)
Can you help?
