Fonction PIN sur l'interface
Pin No. | Symbole | I/O | Description | ||||||||||||
---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
1 | VDD | _ | Power supply pin for logic. | ||||||||||||
2 | VSS | _ | Ground pin, connected to 0V | ||||||||||||
3 | /CS1 | I | Chip select input pin. Interface access is enabled when CS1B is "L" and CB2 is "H". When chip is on-active (CS1B="H" or CS2="L"), D[7:0] pins are high impedance. | ||||||||||||
4 | CS2 | ||||||||||||||
5 | /RES | I | Hardware reset input pin. When RSTB is "L", internal initialization is executed and the internal registers will be initialized. | ||||||||||||
6 | A0 | I | It determines whether the access is related to data or command. A0="H": Indicates that signals on D[7:0] are display data. A0="L": Indicates that signals on D[7:0] are command. |
||||||||||||
7 | R/W | I | Read/Write execution control pin. When PSB is "H", RWR is not used in serial interface and should fix to "H" by VDD.
|
||||||||||||
8 | E | I | Read/Write execution control pin. When PSB is "H",
ERD is not used in serial interface and should fix to "H" by VDD. |

9-16 | D0-D7 | I/O | Data bus line | ||||||||||||
17 | C86 | I | C86 selects the microprocessor type in parallel interface mode.
Please refer to "APPLICATION NOTES" and "Microprocessor Interface" (Section 6) for detailed connection of the selected interface. |
