The answer is interrupts or exceptions. In short, the interrupt vector table contains addresses ( function pointers) of interrupt service /routines and exception handler functions. The interrupt vector table is a table of memory addresses of interrupt/exception handler routines. In other words, it d...
1.What are the various registers in 8085?Accumulator register, Temporary register, Instruction register, Stack Pointer,Program Counter are the various registers in 8085 .2.What is Stack PointerStack pointer is a special purpose 16-bit register inthe Microprocessor, which holdsthe address of the top...
It is a 16 bit special function register in the 8085microprocessor. It keeps track of the thenext memory addressof the instruction that is to be executed once the execution of the current instruction is completed.In other words, it holds the address of the memory locat...
It stored all of it's general purpose registers in RAM, so that Subroutines and Interrupt routines could adopt a completely separate register set just by changing the pointer. It also had no Stack in the traditional sense, it just stored the PC for a return. Logged Best Regards, Chris...
Furthermore, RST6.5, RST7.5, RST5.5 of 8085 microprocessor are some maskable interrupts, whereas Trap of 8085 microprocessor is an example for non-maskable interrupt. Conclusion In brief, maskable and non-maskable interrupts are two types of interrupts. The main difference between maskable and non...
The INTR is a maskable interrupt for the 8085. It has the lowest priority and is also non vectored. When this INTR signal goes into the high state the following things occur / take place: - For every instruction that is executed the 8085 checks the status of this interrupt./ ...
