ST7529
If XCS is set to HIGH while the 8 bits from D7 to D0 are entered, the data concerned is invalid. 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 XCS at HIGH on byte basis to
initialize the serial-to-parallel conversion counter and the register.
When executing the command RAMWR, set XCS to HIGH after writing the last address (after starting the 9th pulse in
case of 9-bit serial input or after starting the 8th pulse in case of 8-bit serial input).
