SPI read
Figure 16. SPI read protocol
The SPI read command is performed with 16 clock pulses. The multiple byte read command
is performed by adding blocks of 8 clock pulses to the previous one.
bit 0: READ bit. The value is 1.
bit 1-7: address AD(6:0). This is the address field of the indexed register.
bit 8-15: data DO(7:0) (read mode). This is the data that is read from the device (MSb first).
bit 16-...: data DO(...-8). Further data in multiple byte reads.
