ZILOG seems to have this habit of changing their die and not telling people. Overall ZILOG is a good chip for selection, price, and are great number crunchers.
On any input you should have at least 150 mv. That means if you have a switch connected to the input directly you are in trouble. Fix: put a 1 Mohm resister on crystal pins.
Factory test mode accidentally may enable if osc1 input gets 9 volts noise for 3 ms. Use of product in noisy environment will cause "mystery" problems Fix: Put clamping diode one side to the VDD and the other side to the osc1 pin.
I have 1560 Z86E0812PEC OTP microcontrollers.
