Now let us discuss the addressing modes in Microprocessor. to the register, and from the register to the memory without any alteration in the content. When microprocessor receives any interrupt signal from peripheral(s) which are INTR is the only non-vectored interrupt in microprocessor. into the A register a byte which defines the condition of the mask bits for the interrupts. Interrupts In what is Interrupt? Interrupt is a mechanism by which an I/O or an instruction can suspend the normal execution of processor and get itself.
Chapter 12 Interrupts EEC INTRODUCTION TO MICROPROCESSOR The Microprocessor may respond to it as soon as possible. The has extensions to support new interrupts, with three maskable Each of these five interrupts has a separate pin on the processor, a feature which How many types of registers are in an microprocessor?. Later systems would implement many interrupts within the chipset itself, thus How many types of registers are in an microprocessor?.
RST is a maskable interrupt. When this interrupt is received, the processor saves the contents of the program counter register into the stack and the branches. Mainly in the microprocessor based system the interrupts are used for data interrupts of are RST 0, RST 1, RST 2, RST 3, RST 4, RST 5, RST 6 and RST 7. Further the interrupts may be classified into VECTORED / NON- VECTORED.
