8.3. Read/Write of data
For both read and write, first set up chip condition (internally CE="H") to CE0="H" and CE1="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".

*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.
