14 Oct 2018 The CALL instruction interrupts the flow of a program by passing control to an internal or external subroutine. An internal subroutine is part of
Description: ACALL unconditionally calls a subroutine at the indicated code address. ACALL pushes the address of the instruction that follows ACALL onto the
This chapter covers the control transfer instructions available in 8051 Assembly language include conditional and unconditional jumps and call instructions. . The assembler will generate an error of out of range if any attempt is made to
function calls and jumps while writing a code in assembly language. Each line of the assembly code is assigned a unique opcode by the assembler as shown . Source : http://www.botskool.com/tutorials/electronics/8051/jump-loop-and-.
This chapter covers the control transfer instructions available in 8051 [] In the second section we examine CALL instructions and their uses. . If any attempt is made to violate this rule, the assembler will generate an error stating the jump is
8051 CALL INSTRUCTIONS. Another control transfer instruction is the CALL instruction, which is used to call a subroutine. Subroutines are often used to perform tasks that need to be performed frequently. This makes a program more structured in addition to saving memory space.The ACALL instruction calls a subroutine located at the specified address. The PC is incremented twice to obtain the address of the following instruction.
The advantage of ACALL over LCALL is that it is a 2-byte instruction while LCALL is a 3-byte instruction. With many 8051 assemblers, you can use JMP for an unconditional jump and CALL to call a subroutine. JMP and CALL are not 8051 instructions. -
