1 = Display module stops in Idle mode
0 = Display module does not stop in Idle mode
GCMDWMK<4:0>: Command FIFO Watermark bits
Sets the command watermark level that triggers the CMDLVIF interrupt and sets the CMDLV flag;
GCMDWMK<4:0> (10000 = Reserved)
10000 = If the number of commands present in the FIFO goes from 16 to 15 commands, the CMDLVIF

GCMDCNT<4:0>: Command FIFO Occupancy Status bits
When the FIFO is full, any additional commands written to the FIFO are discarded.
10000 = 16 commands are present in the FIFO
