Initialize the 9S08SH8 for external oscillator

  • I want to run the 9S08SH8PJ micro from a 4.9MHz external clock source. I have set the ICSC1 register to $80 and the ICSC2 register to $7B but no luck. I also tried many other combinations but it still does not run. Is there any other registers that need to be set up that I missed?

    • I found the issue. Pin 1, the Reset/IRQ/(+15 other functions) was not in the correct state and was keeping the CPU from running. Now it all works well.
