SPI read
Figure 15. SPI read protocol
The SPI read command is performed with 16 clock pulses. A 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: MS bit. When 0, do not increment address; when 1, increment address in multiple
reading.
bit 2-7: address AD(5:0). This is the address field of the indexed register.
bit 8-15: data DO(7:0) (Read mode). This is the data that will be read from the device (MSb
first).
bit 16-... : data DO(...-8). Further data in multiple-byte reading.
