Every write command starts with a high to low
transition of CS and ends by a low to high
transition of CS after 32 periods of the serial
data clock (SCLK). MLX90313C reads the data
present on SDI on the rising edge of the clock.
With a delay of 8 periods of the serial clock, the
SPI will repeat the opcode, address and the first
8 bits of data on pin SDO. This allows the
external master to check command and address
and terminate the operation in case of an error
by forcing CS high before the end of the
complete command cycle, i.e. before the end of
the 32 clock periods.
The read command is build up similarly, except
that no data has to be passed of course. On
SDO the opcode will be followed directly by the

requested data, the address is not returned in
this case.
The data on SDO is valid on the rising edge of
the clock. In case of a read command, the SPI
will output the data on SDO starting on the 25
rising edge of the clock (after CS low) as
indicated in the figure above.
Timing/speed
The baud-rate depends on the serial data clock
(SCLK) supplied by the master controller and is
limited to 125kb/s. The timing requirements are
given in the figure and table below
