- Set to maximum (i.e. 0x3FF). This register is used
- Set to 0 to start RGB sequencing at the first LUT entry.
- Set all the banks to 0.
- At 4BPP this makes no difference however it will affect
- Write 16 RGB triplets to setup the LUT for 4BPP operation.
- The LUT is 16 elements deep, 4BPP uses all the idices.
- '0' configures the GPIO pins for input (power on default)
- This step has no reason other than it programs the GPIO
for split screen operation and should be set to 0
during initialization.
