Which of the microcontroller's pins are most useful, along with their functions?

Recommended Posts

LE: As Harvard architecture is the foundation of the 8051. The program and data memory are connected externally separately. 16 lines are used to access this external memory, of which 8 lines are used as data lines in addition to serving as lower order 8 lines of a 16-bit external address. We utilize an 8-bit external latch to make these 8 lines function first as address lines and then as 8 lines for data. The control signal for latching the low byte of the address during access to external memory is provided by the Address Latch Enable output pulse.
