To select EasyScale interface, after tes_delay delay from EN low to high, drive EN pin to low for more than tes_det before tes_win expires.
Acknowledge condition active 0, this condition is only applied when the RFA bit is set to 1. To use this feature, master must have an open drain output, and the data line needs to be pulled up by the master with a resistor load.
