SPI Interface Modes
There are two SPI modes: read and write.
3.3.2.1
Read Mode
Read communication always takes place in pairs of bytes. A read request of 2 bytes is sent on the MOSI line. The
content of the addressed register, one byte, is dumped on the MISO line during the transmission of the second byte on
the MOSI. The formats of one byte are the following:
