8051/8052 Instruction: LCALL

Function:Long Call
Syntax:LCALL code addr

LCALL code addr0x1232None

Description: LCALL calls a program subroutine. LCALL increments the program counter by 3 (to point to the instruction following LCALL) and pushes that value onto the stack (low byte first, high byte second). The Program Counter is then set to the 16-bit value which follows the LCALL opcode, causing program execution to continue at that address.
