인터페이스 핀 기능

Pin No. 기호 I/O 설명
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.
C86 MPU Type RWR Description
H 6800 series R/W Read/Write control input pin.
R/W="H":read
R/W="L":write.
L 8080 series /WR Write enable input pin.
Signals on D[7:0] will be latched at the rising edge of /WR signal.
 
8 E I Read/Write execution control pin. When PSB is "H",
C86 MPU Type ERD Description
H 6800 series E Read/Write control input pin.
R/W="H": When E is "H", D[7:0] are in output mode.
R/W="L": Signals on D[7:0] are latched at the falling edge of E signal
L 8080 series /RD Read enable input pin.
When /RD is "L", D[7:0] are in output mode.

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.
PSB C86 Selected Interface
"H" "H" Parallel 6800 Series MPU Interface
"H" "L" Parallel 8080 Series MPU Interface
"L" "X" Serial 4-Line SPI Interface

Please refer to "APPLICATION NOTES" and "Microprocessor Interface" (Section 6) for detailed connection of the selected interface.
18 P/S I PSB selects the interface type: Serial or Parallel.
