Only SFR addresses ending ‘0’ or ‘8’ are bit-addressable Pratik Mahajan Sorry Andy you are correct I just read it till the end of SFRs and didn’t notice the next page – the information is given bit addressable way however they are not bit addresssable. I know that it is not customary to include the At89cc51re2 name in bitdefs; I, however find it a great advantage. Propaga- tion also varies from output to output and component.


To prevent bus conflicts on the MISO line, only one slave should be selected at a time by the Master for a transmission.
