Table 14-34. RF interface set-up
14.12.2.6.3
Data transmission
To handle the transmission data by interrupt, enable the RF interface transmission interrupt in the interrupt handler
of the circuit.
We need to send the start sequence first. The start sequence is defined as a protocol violation. To send a protocol
violation, the encoder has to be disabled by clearing RfifEnCod = 0. We then can write for instance “00000000” to
RfifTx.
At occurrence of the interrupt, the start sequence was transferred to the shift register and the FIFO is empty. The
encoder is to be enabled by setting RfifEnCod = 1. We do not need to wait until the start sequence transmission is
completed, since the modification of the bit RfifEnCod is taken into account only at the transfer of the next byte
from the FIFO to the transmission shift register. The first 4 bytes of the message can then be written to RfifTx.
At each occurrence of the interrupt, 4 bytes of the message can be written to the FIFO until the end of the message
is reached. The whole operation starts over again for the next message.
