It is an 8- bit microprocessor designed by Intel in 1977 pointer using NMOS technology. TMOD 89h Timer/ Counter 0 and 1 program Modes GATE1 C/ T1# M11 M01 GATE0 C/ T0# M10 M00. Due to this 8085 UP has 16 bit Program Counter and Stack pointer. Program counter and stack pointer in 8051 datasheet. Diese Architektur ist datasheet speziell für den Einsatz in Mikrocontrollern neu entwickelt und löst damit die bisherigen and ARM7- pointer basierten Controller weitestgehend ab. pc sp adressIf the program counter , stack pointer were only 8- bits wide the processor would be able to address only 256 address locations. Relative branch instructions supply an 8- counter bit signed offset which is added to datasheet the PC. It has the following configuration: 8- bit data bus 16- bit address datasheet bus, which can address upto 64KB A 16- bit program counter A 16- bit stack pointer.

Counter pointer

When the 8051 is reset, the stack pointer is set to address 07h. This means the stack area will begin at address 08h. Register bank 0, the default register bank, has eight registers that occupy addresses 00h through 07h. Popping r0 off the stack involves extracting the value from where the stack pointer points then adjusting that stack pointer up. Halt instruction simply leaves program counter where it is, an infinite loop of sorts. Hopefully from that description, it will become clear.

The AVR Stack Pointer. The AVR 8- bits microcontroller stack pointer can either consist of a single I/ O register SPL ( Stack Pointer Low) or two ( 2) I/ O registers SPL and SPH ( Stack Pointer High). The size of the stack pointer depends on the amount of data memory a microntroller contains.
