9 / 48 page  ST7577 Ver 1.0a 9/48 2008/02/14 RWR_A (for Port-A) RWR_B (for Port-B) I Read/Write execution control pin (PS[0:1]=[L:H]). PS2 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 clock input pin The data on D0 to D7 are latched at the rising edge of the /WR signal. When in the serial interface, left it connected to VDD. * MODE pin will select one of two RWR pins. The unused one should be left floating. 1* 1* ERD_A (for Port-A) ERD_B (for Port-B) I Read/Write execution control pin (PS[0:1]=[L:H]). PS2 MPU Type /RD(E) Description H 6800-series E Read/Write control input pin R/W= “H”: When E is “H”, D0 to D7 are in an output status; R/W= “L”: The data on D0 to D7 are latched at the falling edge of the E signal. L 8080-series /RD Read enable clock input pin. When /RD is “L”, D0 to D7 are in an output status. When in the serial interface, left it connected to VDD. * MODE pin will select one of two RWR pins. The unused one should be left floating. 1* 1* When using 8-bit parallel interface: 6800, 8080 8-bit bi-directional data bus that is connected to the standard 8-bit microprocessor data bus. When chip select is not active, D0 to D7 is high impedance. When using serial interface: 4-LINE D0: serial input clock (SCLK); D1, D2, D3: serial input data (SDA), must be connected together; D4~D7 must be connected to VDD (not used). When chip select is not active, D0 to D7 is high impedance. D7_A …D0_A (for Port-A) D7_B …D0_B (for Port-B) I/O When using serial interface: 3-LINE D0: serial input clock (SCLK). D1, D2, D3: serial input data (SDA), must be connected together; D4~D7 must be connected to VDD (not used). When chip select is not active, D0 to D7 is high impedance. 8* 8* |
