TDA5235
Functional Description
Chapter 2.5.2 and Chapter 2.5.5. The data which is read from the RX FIFO is
accompanied by information which contains the status of the respective receive
operation. Note that the availability of received data packets is communicated via alerts
in the control interface.

Data interface for the Packet Oriented FIFO Mode
Packet Oriented Transparent Payload Mode (POTP)
This mode is very similar to POF Mode as data which is going into FIFO is also available
via RXD and RXSTR signals (see Chapter 2.5.3 Digital Output Pins).

Data interface for the Packet Oriented Transparent Payload Mode
In the TDA5235, there are specific digital output lines (PPx pin) for the Bi-phase decoded
data and an appropriate Strobe signal. During inactivity of the receiver, the line is in
default mode switched to low.
