Setting the RES signal to Low level can initialize the
following registers.
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 = h i g h : D a t a of DB0~DB7 c a n b e r e a d b y 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
Data/Instruciton
D/I=high: Indicates that data of DB0~DB7 is display
data.D/I=low: Indicates that data of DB0~DB7 is
instruction.
