1.6.2
TDA523x has integrated all means to process incoming ASK or FSK modulated
Manchester-coded bit streams, and convert them into pure data, which can be read out
via SPI by the host processor.
Figure 3
The Manchester-coded bit stream is decoded by the Manchester Decoder into a bit
stream containing the wake-up pattern, the TSI (Telegram Start Identifier) and the
payload. The Framer separates the payload and stores it in the FIFO. An interrupt is
generated and data can be read from the FIFO by the host processor via SPI.
1.6.3
The TDA523x offers a fully autonomous Self Polling Mode, in which the RF input signal
is scanned for valid data signals base on programmable timing. The host processor is
not burdened with this task, so its full processing power is available for other tasks, or
the host processor may stay in a power save, or sleep mode. When valid data has been
