... Bi-phase encoding Binary data 0 Memory output Modulator control The P4069 additionally holds a unique 64 bit read only identification code, which can be accessed by using the Read ROM command. Manchester encoding One bit period lasts 64 (or 32) field frequency periods (512 (or 256) µs at 125 kHz). The Manchester coding shows a transition from ON to OFF or from OFF the middle of bit period ...
