Hi all,

I have a question about the I/O pin protection og HCS12 microcontrollers. I am designing additional board which will be used along the CARDS12 board from elektronikladen, and I want to make some interface circuit for I/O pins protection.
Does anybody know that HCS12 I/O pins are already protected by diodes (connected to GND and VCC) for protection against overvoltage?

Thanks for any answer,
