Data
Carrier Burst > 550 us

WAKE
Clear_wake
In case the data correlation is disabled ( R1<1> =0), the AS3930 wakes up upon detection of the carrier frequency only, as shown in Figure 17 . In
order to ensure that AS3930 wakes up, the carrier burst has to last longer than 550 μs. There are two possibilities to set AS3930 back to
listening mode: either the microcontroller sends the direct command clear_wake via SDI, or the time out option is used ( R7<7:5> ). In case the
latter is chosen, then the AS3930 is automatically set to listening mode after the time defined in T_OUT ( R7<7:5> ), counting starts at the low-to-
high WAKE edge on the WAKE pin.
