Question

b) Based on the output setup shown in Figure-1, write an 8051 assembly language program to continuously turn on 4 LEDs (A, B, C, D) and turn off the remaining 4 LEDs (E, F, G, H) alternately. You may use the subroutine PAUSE in Program Listing-1 as the subroutine delay to write a complete program.
