Ax51 Introduction RET

Return From Subroutine

Description  

The RET instruction pops the high-order and low-order bytes of the PC from the stack (and decrements the stack pointer by 2). Program execution resumes from the resulting address which is typically the instruction following an ACALL or LCALL instruction. No flags are affected by this instruction.
