K (T) (Temperature compensation output voltage) is control by TCS1, TCS0 and
formerly environment temperature T.
’TCS is selected by TCS1 and TCS0
’K = 4.005*10^(-3) at 25qC
8.2.34 Display Select Control
(At the time of reset: {GLSB} = 0H, read address: 8H)
GLSB
In 256 color mode, for the segment driver of 4-gradation display, select 4 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 = “0”: Selects 0 as the LSB information on the RAM for 4-gradation
segment driver.
Gradation LSB = “1”: Selects 1 as the LSB information on the RAM for 4-gradation
segment driver.
