I/O
Description
Read / Write execution control pin
PS1 MPU Type E_RD
Description
Read/Write control input pin
− RW = "H": When E is "H", DB0 to DB7 are in an
H 6800-series
E
output status.
I
− RW = "L": The data on DB0 to DB7 are latched at
the falling edge of the E signal.
L 8080-series
Read enable clock input pin
/RD 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 (PS0 = "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.
