Hi jtjans,
You are right. After some experiments, I may have some guessing for the migration from MC9S08GT60 to MC9S08GT60A.
1. Since all the stack and I/O mappings are not changed so that all the logics keep the same;
2. Some input impedance for pins may have been changed , thus injecting more current for 60A than for 60 type.
Based on my measurement, the impedance change is significant, do you have the same feeling?
Pity thing is that, I couldn't find any open source documents to reveal these, check pin by pin is really time-consuming..
Best :smileyhappy:
