Both the Read Register and Write Register commands are completed in 16 clock pulses or
in multiple of 8 in case of multiple bytes read/write. Bit duration is the time between two
falling edges of SPC. The first bit (bit 0) starts at the first falling edge of SPC after the falling
edge of CS while the last bit (bit 15, bit 23, ...) starts at the last falling edge of SPC just
before the rising edge of CS.
bit 0: RW bit. When 0, the data DI(7:0) is written into the device. When 1, the data DO(7:0)
from the device is read. In latter case, the chip will drive SDO at the start of bit 8.
bit 1: MS bit. When 0, the address will remain unchanged in multiple read/write commands.
When 1, the address will be auto incremented in multiple read/write commands.
bit 2-7: address AD(5:0). This is the address field of the indexed register.
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 7.
SPI read protocol
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.
