Specyfikacja

Funkcja pinów interfejsu

Pin No. Symbol Funkcja
1 VDD Power supply
2 NC No connection
3 VSS Ground
4 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)
5 RSTB Reset input pin. When RSTB is “L”, internal initialization procedure is executed
6 /RD(E) Read / Write execution control pin. (This pin is only used in parallelinterface)
MPU Type ERD Description
6800-series E Read/Write control input pin.
R/W = "H": When E is "H", data bus is in output status.
R/W = "L": The data are latched at the falling edge of the E signal.
8080-series /RD Read enable input pin.
When /RD is "L", data bus is in out put status.
This pin is not used in serial interfaces and should be connected to VDD1
7~14 D7~D0 The bi-directional data bus of the MPU interface. When CSB is “H”, they are high impedance
If using serial interface:
D0 is the SDA signal in 4-Line & 3-Line interface
D1 is the A0 signal in 4-Line interface
15 /WR/(R/W) Read / Write execution control pin. (This pin is only used in parallel interface)
MPU Type ERD Description
6800-series R/W Read/Write control input pin.
R/W = "H": read
R/W = "L": write
8080-series /WR Read enable input pin.
The data are latched at the rising edge of the /WR signal.
This pin is not used in serial interfaces and should be connected to VDD1
16 A0(SCL) The function of this pin is different in parallel and serial interface
In parallel interface: A0 is register selection input
A0 = "H": inputs on data bus are display data
A0 = "L": inputs on data bus are command
In serial interface: this pad will be used as SCL (serial-clock) input
17 A LED+
18 K LED-
