D[7:6] : 00b, 01b, 10b, or 11b for Color = A, B, C, or D of BANK32.
X[0] = 0; Column address 0 is mapped to SEG0
X[0] = 1; Column address 131 is mapped to SEG0
X[0] = 0; Resume RAM content display. Output follows RAM content.
X[0] = 1; Entire display ON. Output ignores RAM content.
X[0] = 0; Normal display.
X[0] = 1; Inverse display.
Set MUX ratio to N+1 MUX
N=A[5:0]; from 16MUX to 64MUX (0 to 14 are invalid)
A[3:0] = reserved. Set as 0000b
B[7:0] = Set contrast for BANK0. Range 0‐255d. Refer to command
81h.
