• A. Translate a byte in AL using a table index
• B. Transfer data from source to destination
• C. Push the contents of specified source on to the stack
• D. Exchange the contents of source with destination

Hint:

Remember the function of instruction set, and always remember XLAT translates a byte using the value in AL register, and storing the result in AL register.

Answer 1

The Correct Option is A

The XLAT (translate) instruction in the 8086 microprocessor is used for table lookups. It translates a byte from a lookup table in memory, using the AL register as a index. The translated value is stored back into AL. This instruction is used for tasks such as character mapping or code conversions.
