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
1
RF-PASE data reception
Not available
2
Duty cycle
Duty -off ( PDWN_SMD :Low / PDWN_KFSK:High)
3
SRx –bus communication
Be available
4
Battery voltage observation
Be observed
5
RSSI measurement
Not available only for SMD receiver needed
6
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.
