9.5 Data transfer pause
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
