The 8051 architecture allows for external program and
data access through the use of Port 0 and Port 2 as an
external memory interface. The 8051 architecture multiplexes
the data and LSB of address on Port 0, requiring
a 74373 latch for demultiplexing. This means that Port 0
will be directly connected to at least two devices. More
devices may be placed on the bus if an external data
SRAM or memory–mapped peripherals are used.
