6.5 Display Data Transfer 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 DRIVER will reject the
previous its and have reset the interface such that it will be ready to receive command data again when the chip
select line (CSX) is next activated after RESX have been High state. See the following example.

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 line(CSX) is next activated. See the following example.

If1, 2 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 re-transmitting the parameter that was interrupted,
then the parameters that were successfully sent are stored and the parameter where the break occurred is
rejected. The inter face is ready to receive next byte as show below.
Note: Break can be e.g. another command or noise pulse.
