What is the function of EA pin in 8051 Microcontroller?

making EA pin high(i.e connecting it to +5V) means that microcontroller should look for the code in its internal memory. while making it low(i.e connecting it to GND) means that microcontroller should look for the code in the memory which is externally connected by the user. so when there is no external memory connected, simply tie EA pin to +5V supply.
