13 | CSB | Chip select input pin. CSB=“L”: This chip is selected and the MPU interface is active. CSB=“H”: This chip is not selected and the MPU interface is disabled (D[7:0] are high impedance). |
||||||||||||||||||||||||
14 | RSTB | This pin is reset signal input. When the pin is low, initialization of the chip is executed. Keep this pin HIGH (i.e. connect to VDD) during normal operation. | ||||||||||||||||||||||||
15 | A0 | It determines whether the access is related to data or command. A0 = "H": Indicates that D[7:0] are display data; A0 = "L": Indicates that D[7:0] are control data. This pin is I2C slave address bit (SA0), when I2C interface is selected. |
