Do you know that?
There is a large advantage when reading >1 byte. The XBANKING method goes through the whole rigamarole for every byte. E.g. IIC serial memories can read a full page with one "setup" My typical EE routine is not byte_from_ee = read_ee( ee_address ); but read_ee( ee_address, save_addr, length ); If your app re the EE is single byte always, then - maybe - the XBANKING trick can make a bit of sense. Erik Actually, I think the XBANKING method has the ability to grab 1 - 4 byte data types with a single call into the relevant routine inside XBANKING.A51. Of course, this does little to improve performance if you need to retrieve a large array. --Sasha Jevtic |
