WebMay 29, 2024 · It is implemented by using Call and Return instructions. The different types of subroutine instructions are Unconditional Call instruction – CALL address is the format for unconditional call instruction. After execution of this instruction program control is transferred to a sub-routine whose starting address is specified in the instruction. Stack Memory Allocation in 8051 Microcontroller. The stack is an area of random access memory (RAM) allocated to hold temporarily all the parameters of the variables. The stack is also responsible for reminding the order in which a function is called so that it can be returned correctly. See more The ‘PUSH’ is used for taking the values from any register and storing in the starting address of the stack pointer, i.e., 00h by using ‘PUSH’ … See more It is used for placing the values from the stack pointer’s maximum address to any other register’s address. If we use this ‘POP’ again, then it decrements by 1, and the value stored in … See more The 8051 consists of four input/output related special function registers in which there are totally 32 I/O lines.
