7.1.11. Data Transfer Break and Recovery
If there is a break in data transmission by RESX pulse, while transferring a command or frame memory data or
multiple parameter command data, before Bit D0 of the byte has been completed, then the driver will reject the
previous bits and have reset the interface such that it will be ready to receive command data again when the
chip select pin (CSX) is activated after RESX have been high state.

If there is a break in data transmission by CSX pulse, while transferring a command or frame memory data or
multiple parameter command data, before Bit D0 of the byte has been completed, then the driver will reject the
previous bits and have reset the interface such that it will be ready to receive the same byte re-transmitted when
the chip select pin (CSX) is next activated.

(MPU to Driver)
If a two or more parameter command is being sent and a break occurs while sending any parameter before the
last one and if the host then sends a new command rather than continue to send the remained parameters that
was interrupted, then the parameters which had been successfully sent are stored and the parameter where the
break occurred is rejected. The interface is ready to receive next byte as shown below.
