CS2 Chip select for the right half of the display. Active high
Setting the RES signal to Low level can initialize the
following registers.
14
RES
1. ON/OFF register 0 set (Display off)
2. Display start line register 0 set(display starts from
line 0). After releasing reset, this condition can be
changed only by software.
Read/Write
R/W=high: Data of DB0~DB7 can be read by CPU.
15
R/W R/W=low: Data of DB0~DB7 can be written into LCD
driver IC at the falling edge of E when CS1 and CS2
is high
Data/Instruciton
16
D/I
D/I=high: Indicates that data of DB0~DB7 is display
data.D/I=low: Indicates that data of DB0~DB7 is
instruction.
Enable: When write (R/W=low): Data of DB0~DB7 is

E
latched at the fall of E. When read(R/W=high): Data
is read while E is at high level.
