It will be possible when transferring a Command, Frame Memory Data or Multiple Parameter Data to invoke a pause in the data
transmission. If the Chip Select Line is released after a whole byte of a Frame Memory Data or Multiple Parameter Data has been
completed, then DRIVER will wait and continue the Frame Memory Data or Parameter Data Transmission from the point where it was
paused. If the Chip Select Line is released after a whole byte of a command has been completed, then the Display Module will receive
either the command’s parameters (if appropriate) or a new command when the Chip Select Line is next enabled as shown below.
This applies to the following 4 conditions:
1) Command-Pause-Command
2) Command-Pause-Parameter
3) Parameter-Pause-Command
4) Parameter-Pause-Parameter
