Fig.7.4 External Receiver Circuitry
After hardware reset, the receiver may enter power down state in order to save power consumption. In this
state, the internal clocks are turned off, but the analog level detector is still active to detect signal coming from
the S interface. The power down state is left either by non-INFO 0 signal from S interface or C/I command from
microprocessor.
