Hardware interrupts in 8051 microcontroller datasheet

GENERAL DESCRIPTION The N76E003 is an embedded flash type, 8- bit high performance 1T hardware 8051- based microcontroller. So the handling datasheet of interrupts in the 8051 CPU and in the ARM CPU seem microcontroller different to you because they use fundamentally different schemes for finding the address of the ISR. The Intel MCS- 51 ( commonly termed microcontroller 8051) is a single chip microcontroller ( MCU) series interrupts developed by Intel in 1980 for use in embedded systems. And then in a datasheet,. When a subroutine is completed, Then the execution hardware of main program starts. It includes peripherals for serial microcontroller communication a multi- purpose I/ O port, hardware interrupts, hardware , a timer a JTAG debugger interface. Hardware interrupts in 8051 microcontroller datasheet. The architect of the instruction set of the Intel MCS- 51 was John H.

Hardware interrupts

Any interrupt can cause the 8051 to perform a hardware call to an interrupt- ­ handling subroutine that is located at a predetermined ( by the 8051 designers) absolute address in program memory. Five interrupts are provided in the 8051. The 8051 Instruction Set 1- 3 Atmel 8051 Microcontrollers Hardware Manual 4316E– 8051– 01/ 07 1. 3 Register Instructions The register banks, containing registers R0 through R7, can be accessed by certain instructions which carry a 3- bit register specification within the opcode of the instruction.

8051” is simply the generic name given to the entire series because it was the first single chip microcontroller solution of the series. Following are six basic intel versions with which the reader should be familiar – other vendors generally construct part numbers from their own prefix and the last two digits of the these intel versions.
