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...
Re: What kind of code is on 1980's, 1990's scope's/etc ? « Reply #1 on: March 23, 2020, 07:03:37 pm » Basically yes. Most equipment I see from this era uses custom code based in C or ASM. So yes, you used your elbow to brush bits on registers, after reading hundre...
Explain briefly what happens when the INTR signal goes high in the 8085 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: ...
Also, it is possible to handle a maskable interrupt after executing the current instruction, but when non-maskable interrupts occur, the current instructions and status are stored in stack for the CPU to handle the interrupt. Examples Furthermore, RST6.5, RST7.5, RST5.5 of 8085 microprocessor ar...
