R/W specifies the type of operation:
Thus, this bit is associated with the presence of information on MOSI (when writing) or MISO (when
reading).

slave. A received byte is considered internally on the eighth falling edge of SCLK. Consequently, the last
received bits, which do not form a complete byte, are lost.
10.3 Configuration Switching
This feature allows for defining two different configurations using two different banks, and for switching
them automatically during wakeup when using a strobe oscillator, or by means of the strobe pin actuation
by the MCU.
