Set the lower nibble of the column address register
using X
address is reset to 0000b after POR.
Set the higher nibble of the column address register
using X
column address is reset to 0000b after POR.
Feedback gain of the internal regulated DC-DC
converter for generating VOUT increases as X
increased from 000b to 111b. After POR, X
100b.

Y
For 64/54/32 MUX modes, set GDDRAM display start
line register from 0-63 using X
There is no need to send the Y
parameters.
Display start line register is reset to 000000 after POR
for all MUX modes.
Set the DC-DC multiplying factor from 2X to 5X.

Remarks: The POR default boosting level is determined
by hardware selection pin, B0 & B1.
Select contrast level from 64 contrast steps. Contrast
increases (VOUT decreases) as X
increased from 000000b to 111111b. X
