External reset pin. Only if the power on reset be used, the
XRESET pin could be fixed to VDD.
Low active.
Select registers.
0: Instruction register (for write)
1: Data register (for write and read)
Select read or write(In parallel mode).
0: Write
1: Read
Starts data read/write. (“E” must connect to “VDD” when
serial mode is selected.)
Chip select in parallel mode and serial interface(Low
active). When the CSB in falling edge state ( in serial
interface ), the shift register and the counter are reset.
DB0~DB3 are four low order bi-directional data bus pins.
DB0~DB3 are used for data transfer and receive between
the MPU and the ST7036.
These pins are not used during 4-bit operation and must
connect to VDD.
DB4~DB7 are four high order bi-directional data bus pins.
DB4~DB7 are used for data transfer and receive between
the MPU and the ST7036. DB7 can be used as a busy flag.
In serial interface mode DB7 is SI(input data),DB6 is
SCL(serial clock).
In I
address A0, DB5 DB4 DB3 are SDA –out, DB2 DB1 are
SDA-in and D0 is SCL.
SDA and SCL must connect to I
connecting a resister between SDA/SCL and the power of
