3.1.4.  STAND-BY MODE: 
 
The Stand by Mode is entered by an interrupt from the RxD input (falling edge interrupt) when the SRx 
is in the sleep mode. In Stand by Mode the SRX-Bus communication is fully available for 500 ms after 
the SRx oscillator is stable.  
 
 
 In the STAND-BY Mode the following functionalities are available: 
 
 
Parameter 
description 
RF-PASE data reception  
Not available  
Duty cycle 
Duty -off ( PDWN_SMD :Low / PDWN_KFSK:High) 
SRx –bus communication 
Be available  
Battery voltage observation 
Be observed 
RSSI measurement 
Not available only for SMD receiver needed 
Contact- cleaning 
Be available 
  
 
 
 
Note: In SLEEP MODE the SRx does go into the micro controllers stop operation, where the system clock is 
switched off to save power. Thus leaving the SLEEP MODE takes some time until the oscillator is properly 
operating again. 
 
  
Note: The function of both Sleep mode and Stand-by mode is realization depending on systematically 
implementation with a host module for the current consumption saving strategy.
