When set, the driver will use the Ultra-Deep Power-Down command instead
of the default Deep Power-Down one to put the chip into low power mode.
From the driver perspective, as it does not rely on the contents of the
SRAM buffers in the chip, the difference between the Deep and Ultra-Deep
Power-Down modes is that the chip consumes far less power in the latter
but needs some more time to enter this mode and to exit from it.
