bit 8-15 : data DI(7:0) (write mode). This is the data that will be written into the device (MSb
first).
bit 8-15 : data DO(7:0) (read mode). This is the data that will be read from the device (MSb
first).
In multiple read/write commands further blocks of 8 clock periods will be added. When MS bit is
0 the address used to read/write data remains the same for every block. When MS bit is 1 the
address used to read/write data is incremented at every block.
The function and the behavior of SDI and SDO remain unchanged.
SPI Read
Figure 5.
The SPI Read command is performed with 16 clock pulses. Multiple byte read command is
performed adding blocks of 8 clock pulses at 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.
