(c) Description
This command does not perform any operation. This command simply fetches the next instruction.
However when the INT bit is set to 1 in this command, after this command has been fetched, the
INT bit in the status register (SR) is set to 1, INT No is saved in the interrupt command ID register
(ICIDR), and the drawing operation is halted. Clearing the INT bit in the status register (SR)
restarts the drawing operation from the next command.
