Notes
1. Calibration mode may not be entered if the SEAL bit has been set. Programming is only possible when in calibration
2. If the factory defaults OTP bit has been programmed to 1, then the Set factory defaults instruction is ignored and the
3. These values can set by the module maker. If the factory defaults OTP bit has been set, then these values cannot

0 = display off; 1 = display on
0 = normal display; 1 = inverse video mode
0 = normal display; 1 = all pixels on
0 = no Y mirroring; 1 = Y mirroring
0 = charge pump off; 1 = charge pump on
0 = normal data order; 1 = MSB/LSB transposed for RAM data
