The device consumes the most power during RF emissions in Tag Detection mode

(Figure 7). The User can regulate the mean consumption by modifying the period between

bursts (Wuperiod).

In the above figure, yellow represents the 27.12-MHz (HFO) oscillator and the device power consumption

is in green.
