If /CS is set to HIGH while the 8 bits from D7 to D0 are entered, the data concerned is invalidated. Before entering
succeeding sets of data, you must correctly input the data concerned again.
In order to avoid data transfer error due to incoming noise, it is recommended to set /CS at HIGH on byte basis to
initialize the serial-to-parallel conversion counter and the register
When executing the command RAMWR, set /CS to HIGH after writing the last address. The internal shift register and
the counter are reset when /CS =H.
