I hav interfaced adc 0808 to at89c51
so for this i hv connected SOC signal to P3.0 and EOC signal to P3.1.
So my question is that how should i operate my port 3 whether as an input or as an output. Because i hv wrote my program in assembly language directly without making port 3 as an input or output.
SETB P3.0
JB P3.1, L2
CLR P3.0
CLR P3.1
MOV PORT1, #FFH
MOV PORT1, A [Data is present in port 1 and i hv configured port 1 as an input already plz do help me.]
