gradations from 8 gradations using the 2 bits written to the corresponding RAM
area and the 1 bit supplemented by the gradation LSB circuit. Supplement the 1
bit of data by setting the gradation LSB register (GLSB).
Gradation LSB = “1”: Selects 1 as the LSB information on the RAM for 4-gradation
segment driver.
In 65K color mode, select the 48 gradation level from the 32 gradation palette. In
4096-color mode, select the 16 gradation level from the 32 gradation palette. In
256 color mode, just select a setting lower than 8 gradation.
