OPERATION
SCE is going low
function set: PD = 0, V = 0;
select extended instruction
set (H = 1)
set PRS to higher
programming range
(PRS = 1)
set VPR: VPR* =
(a + 132* × b) = 8.596 V
(required voltage is
dependent on liquid crystal
operating environment)
function set: PD = 0, V = 0;
select normal instruction set
(H = 0)
display control: set normal
mode (D = 1 and E = 0)
set data order: DO = 0
option available in 3-line
SPI for setting display data
length command (7 shown)
