received, the host processor is alerted by an interrupt, and the data payload is available
from the FIFO. Invalid signals are ignored.
The TDA523x offers different programmable scanning modes, and criteria to identify
valid wake up patterns, TSIs, and payloads.
Selectable Wake-Up Criteria include detection of a valid data rate, a random
Manchester-coded pattern, a chain of equal Manchester-coded bits, or a specific pattern.
Before initiating an interrupt also the TSI must match up to a programmed pattern;
optionally the data stream may be scanned for up to 16 bytes of a Message Identifier.

TDA523x has two switchable register sets, allowing scans based on up to two different
configurations from different transmitters. Transmissions may differ in sub-channel,
modulation, wake-up criterion, data rate, TSI, message identifier, packet length, etc.
In Self Polling Mode configurations are switched autonomously; in Slave Mode,
configurations are switched by changing a single register bit.
1.6.5
TDA523x supports up to 17 subchannels: 1 center channel, 8 channels above, and 8
channels below the center channel frequency. The frequencies for the channels are fixed
and depend on the system frequency and the selected band. Additional information is
provided in chapter
In Self Polling Mode up to 3 Channels per Receiver Configuration may be scanned
automatically.
