Figure 17. RSSI Operation in Continuous Mode

Standby: LVD Mode

The SPI is deselected. CONFB is set to high level and STROBE to low level in order to enter this mode.

Nothing is sent and all incoming data are ignored until CONFB and SEB go low to switch back to

configuration mode.

Standby/LVD mode allows minimum current consumption to be achieved. Depending upon the value of

the LVDE bit, the circuit is in standby mode (state 60) or LVD mode (state 5 and 20).

LVDE = 0: The receiver is in standby; consumption is reduced to leakage current (current state after POR).

LVDE = 1: The LVD function is enabled; consumption is in the range of tens of microamperes.

The only way to exit this mode is to go back to configuration mode by applying a low level to CONFB and

a high level to STROBE.
