Occurence of a Pulse at the End of the Data Stream
Controlled Noise Suppression
by the Microcontroller (see
Figure 31)
If the bit Noise_Disable (see Table 10) in the OPMODE register is set to 0, digital noise
appears at the end of a valid data stream. To suppress the noise, the Pin POLL-
ING/_ON must be set to Low. The receiver remains in receiving mode. Then, the OFF-
command causes the change to the start-up mode. The programmed sleep time (see
Table 8) will not be executed because the level at Pin POLLING/_ON is low, but the bit
check is active in that case. The OFF-command activates the bit check also 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 to suppress the noise is recommended if the data stream is not Manchester or
Bi-phase coded.
