An $8085$ microprocessor executes $“STA 1234H”$ with starting address location $1FFEH$ (STA copies the contents of the Accumulator to the $16$- bit address location). While the instruction is fetched and executed, the sequence of values written at the address pins $A_{15} – A_8$ is

  1. $1FH, 1FH, 20H, 12H$
  2. $1FH, FEH, 1FH, FFH, 12H$
  3. $1FH, 1FH, 12H, 12H$
  4. $1FH, 1FH, 12H, 20H, 12H$
