8. Option Bits Some of the option bits on the older parts may not work as expected For example programming ROM Protect on the older Z86E04 E08s no Mask revision automatically results in Low Noise EMI Consult your local Zilog sales office if you have specific questions about the parts you are using Use ROM Protect and EPROM test kill on production parts only Oth erwise you will make it extremely difficult to troubleshoot a codgprob lem Additionally these parts may appear blank but attempts at re programming could destroy the parts Page 11
