0xAF = Display ON
Sets the VCOMH voltage level 000000‐011111.
A[5:0] = 1xxxxx = 1.0*VREF
Sets the precharge voltage level 00000000‐00011111
A[7:0] = 1xxxxxxx connects to VCOMH
A[7:0] = 001xxxxx equals 1.0*VREF
A[3:0] = P1. Phase 1 period of 1‐15 DCLK clocks
A[7:4] = P2. Phase 2 period of 1‐15 DCLK clocks
Sets number of DCLKs (K) per row. Range 2‐158DCLKs.
K = P1 + P2 + GS15 pulse width (RESET values: 3 + 5 + 29)
A[3:0] = Define the divide ratio of the display clocks. Range 1‐16
Divide ratio = A[3:0] +1
A[7:4] = Set the Oscillator Frequency. Frequency increases with the
value of A[7:4]. Range 0000b~1111b.
Sets the gray scale level. Range 1‐15
