Question

Write an ALP to find the 2's complement of an 8-bit number stored at 3301H. Store the result at memory location 3302 H.​

Answer 1

Answer:

A is an 8-bit accumulator which is used to load and store the data directly

LDA is used to load accumulator direct using 16-bit address (3 Byte instruction)

CMA is used to complement content of accumulator (1 Byte instruction)

STA is used to store accumulator direct using 16-bit address (3 Byte instruction)

ADI is used to add data into accumulator immediately (2 Byte instruction)

HLT is used to halt the program
