2.4.5.5
In Self Polling Mode TDA523x autonomously polls for incoming RF wake up data
streams. There is no processing load on the host microcontroller. When a wake up
criterion has been found, the mode is changed to Run Mode Self Polling for automatic
verification of TSI, MIDs and transfer of data to the FIFO.
Self Polling Mode is entered by setting the register bit MSEL to 1.
Configuration changes are allowed only by switching to SLEEP mode, and returning
after reconfiguration.
The Polling Timer Unit controls the timing for scanning (On Time) and sleeping (Off
Time). Two independent configuration sets (A and B) are automatically switched, thus
enabling scanning from different transmit sources. Additionally, within each configuration
as many as 3 different frequency channels may be scanned to allow multi-channel
applications.

The Wake Up Generation Unit identifies whether an incoming data pattern matches
with the configurable wake up criterion.
After receiving the wake up pattern, modulation can be switched.
