14.10. Reading/Writing Data via the SPI-Bus Interface
For both read and write, first set up chip condition (internally CE="H") to CE="H", then specify the 4-bits address, and
finally read or write in 8-bits units. Both read and write use MSB-first. In continuous operation, objected address is auto
incremented. Auto incrementing of the address is cyclic, so address "F" is followed by address 0.
14.10.1 Write / Read and Bank Select
R/W and Register bank are specified by the four bits mode setting code.
When writing data, the data needs to be entered in 8-bits units.
If the input of data in 8-bits unit is not completed before CE input falls, the 8-bits data will not be written properly
at the time CE input falls.
14.10.3 Read of Data
1) One-shot reading
