When an 8051 microcontroller power up, the stack pointer contained value is 07, by default, as shown in the above figure. If we perform ‘PUSH’ operation, then the stack pointer address will be increased and shifted to another register. To avoid this problem, before starting the program, w...
No. The stack pointer operates on the stack. The frame pointer operates on the frame. Very often, the frame is located in the stack, but it ain't necessarily so. > > A) Please let me know what is the difference between these two >pointers. The stack pointer always points to the top...

The stack pointer register in a computer is made available for general purpose use by programs executing at lower privilege levels than interrupt handlers. A set of instructions in such programs, excluding stack operations, stores data other than the stack pointer, such as operands, and the like...
However, the issue isn't really commoning. It's whether there is a GC point between the instruction that sets the register and any later instruction that consumes the register. In the first set of pasted trees, typeOfBuffer is unresolved, so evaluation of n4145n has generated a sequence tha...

As the stack is a section of a RAM, there are registers inside the CPU to point to it. The register used to access the stack is known as the stack pointer register. The stack pointer in the 8051 is 8-bits wide, and it can take a value of 00 to FFH. When the 8051 is initialize...
