SPI Data table

SPI Data table

SPI communication data format.
It has an unsigned 8-bit size 4 array structure.
There may be changes due to the addition of functions, so please check occasionally.
The policy is not to change the order of the currently determined parameters even when changing.
See the table below for details.
