Data/Instruciton
D/I=high: Indicates that data of DB0~DB7 is display data.
Read/Write
R/W=high: Data of DB0~DB7 can be read by CPU.
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
Enable: When write (R/W=low): Data of DB0~DB7 is
latched at the fall of E. When read(R/W=high): Data
is read while E is at high level.
DB0~DB7 Data Bus: 3-state I/O common terminal.

Setting the RES signal to Low level can initialize the
following registers.

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.
