In configuration mode a configuration word of up to 15 bytes is downloaded to
nRF2401. This is done through a simple 3-wire interface (CS, CLK1 and DATA). For
more information on configuration please refer to the nRF2401 Device configuration
chapter on page16.

Stand by mode is used to minimize average current consumption while maintaining
short start up times. In this mode, part of the crystal oscillator is active. Current
consumption is dependent on crystal frequency (Ex: 12 µA @ 4 MHz, 32 µA @ 16
MHz). The configuration word content is maintained during stand by.

In power down the nRF2401 is disabled with minimal current consumption, typically
less than 1µA. Entering this mode when the device is not active minimizes average
current consumption, maximizing battery lifetime. The configuration word content is
maintained during power down.
