output status.
− RW = “L”: The data on DB0 to DB7 are latched at
the falling edge of the E signal.

/RD
Read enable clock input pin
When /RD is “L”, DB0 to DB7 are in an output status.
8-bit bi-directional data bus that is connected to the standard 8-bit microprocessor data
bus. When the serial interface selected (PS = "L");
I/O
− DB0 to DB5: high impedance
− DB6: serial input clock (SCLK)
− DB7: serial input data (SID)
When chip select is not active, DB0 to DB7 may be high impedance.
