It has separate 8 bit parallel input and output ports, which can interface to a parallel output ADC such as the AD7575 or ADC0804. You will need extra circuitry to generate the baud rate clock, control the MUX etc. Here is an example circuit (only has one input channel!):- retired.beyondlogic.org/serial/serial2.htm | |
