4.3.4 8080-series parallel interface

If CS is low after the positive edge of RES, the 8080 parallel interface is ready to receive or transmit data.

While CS pin is high the 8080 Parallel interface is kept in reset.

Write Mode

Data are latched on WR rising edge.

Read Mode

Data are output on D0-D7 bus on RD rising edge. Data Bus is set in high impedance mode when RD is set to

logic 1.

Accordingly to R bit value I2C Address or Status Byte is output on D0-D7 bus.
