Why Dummy Byte?

neo nav

While reading EEPROMs or some other, we have to send DUMMY Bytes in order to receive Results?
Why it is required?

    I'm assuming you mean SPI EEPROMs. Well, you have to generate clock pulses in order to shift data out of the EEPROM. It appears that with most (if not all) SPI masters the only way to generate clock pulses is to send bytes. If you think about it, it makes sense.
