Figure 10-3. Occurrence of a Pulse at the End of the Data Stream
Digital noise appears at the end of a valid data stream if the bit Noise_Disable (see

must be set to low. The receiver remains in receiving mode. The OFF command then causes a
change to start-up mode. The programmed sleep time (see
cuted because the level at pin POLLING/_ON is low; however, the bit check is active in this
case. The OFF command also activates the bit check if the pin POLLING/_ON is held to low.
The receiver changes back to receiving mode if the bit check was successful. To activate the
polling mode at the end of the data transmission, the pin POLLING/_ON must be set to high.
This way of suppressing the noise is recommended if the data stream is not Manchester or
Bi-phase coded.
