Read / Write execution control pin
8-bit bi-directional data bus that is connected to the standard 8-bit microprocessor data
bus. When the serial interface selected (PS = "L");
When chip select is not active, DB0 to DB7 may be high impedance.
These are pins for IC chip testing.
They are set to Open.
