Read & write protocol
CS is the Serial Port Enable and it is controlled by the SPI master. It goes low at the start of
the transmission and goes back high at the end. SPC is the Serial Port Clock and it is
controlled by the SPI master. It is stopped high when CS is high (no transmission). SDI and
SDO are respectively the Serial Port Data Input and Output. Those lines are driven at the
falling edge of SPC and should be captured at the rising edge of SPC.
Both the Read Register and Write Register commands are completed in 16 clock pulses or
in multiple of 8 in case of multiple byte 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.
