|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
| 1 | IRS | I | This terminal selects the resistors for the V0 voltage level adjustment. IRS = “H”: Use the internal resistors IRS = “L”: Do not use the internal resistors. The V0 voltage level is regulated by an external resistive voltage divider attached to the VR terminal |
|||||||||||||||
| 2 | /HPM | I | This is the power control terminal for the power supply circuit for liquid crystal drive. /HPM = “H”: Normal mode /HPM = “L”: High power mode(Default) |
|||||||||||||||
| 3 | P/S | I | This is the parallel data input/serial data input switch terminal. P/S = “H”: Parallel data input. P/S = “L”: Serial data input. The following applies depending on the P/S status:
When P/S = “L”, D0 to D5 fixed “H”. /RD (E) and /WR (R/W) are fixed to either “H” or “L”. With serial data input, It is impossible read data from RAM |
|||||||||||||||
| 4 | C86 | I | This is the MPU interface selection pin. C86 = “H”: 6800 Series MPU interface. C86 = “L”: 8080 Series MPU interface |
|||||||||||||||
| 5 | VR | I | Output voltage regulator terminal. Provides the voltage between VSS and V0 through a resistive voltage divider. IRS = “L” : the V0 voltage regulator internal resistors are not used. IRS = “H” : the V0 voltage regulator internal resistors are used. |

| 22~29 | D7~D0 | I/O | Data bus line | |||||||||||||||
| 30 | /RD(E) | I | • When connected to 8080 series MPU, this pin is treated as the “/RD” signal of the 8080 MPU and is LOW-active. The data bus is in an output status when this signal is “L”. • When connected to 6800 series MPU, this pin is treated as the “E” signal of the 6800 MPU and is HIGH-active. This is the enable clock input terminal of the 6800 Series MPU. |
|||||||||||||||
| 31 | /WR(RW) | I | • When connected to 8080 series MPU, this pin is treated as the “/WR” signal of the 8080 MPU and is LOW-active. The signals on the data bus are latched at the rising edge of the /WR signal. • When connected to 6800 series MPU, this pin is treated as the “R/W” signal of the 6800 MPU and decides the access type : When R/W = “H”: Read. When R/W = “L”: Write. |
|||||||||||||||
| 32 | A0 | I | This is connect to the least significant bit of the normal MPU address bus, and it determines whether the data bits are data or command. A0 = “H”: Indicates that D0 to D7 are display data. A0 = “L”: Indicates that D0 to D7 are control data. |
|||||||||||||||
| 33 | /RES | I | When RES is set to “L”, the setting are initialized. | |||||||||||||||
| 34 | /CS1 | I | This is the chip select signal. |
