When an interrupt occurs, the microcontroller runs the ISR. At the start of execution, the ISR disables the interrupt services of all other devices, stopping the instruction that's currently processing and saving its configuration in a register. Then it will load the interrupt'sprogram counterfrom...
A microcontroller is a sophisticated single-chip microcomputer that integrates all essential computing elements onto a single integrated circuit (IC)...

we will define the interrupt vector table (IVT). Secondly, we will see the role of IVT for interrupts and exceptions processing in microcontrollers or microprocessors. After that, we will see the interrupt vector table of TM4C123G ARM Cortex M4 microcontroller. ...
addressable memory space of TM4C123G microcontrollers. TM4C123G is a 32-t bit microcontroller and an addressable memory space starts from 0x0000_0000 and ends on 0xFFFF_FFFF. The starting addresses that are from 0x0000_0000 contains the interrupt vector table. As shown in the figure below...
Analog to Digital Converter & Digital to Analog Converter:These are the convertor used inside the microcontroller in order to convert the signal fromanalog to digitaland vice versa. Interrupt control:The name itself is self explanatory and it helps to perform the program without any interruption. ...
What is PWM in microcontroller? Pulse Width Modulation(PWM) is a technique where the width of digital pulses is adjusted to generate different average dc voltages. Most microcontrollers have a built-in timer that can be used to generate a PWM signal. ...
AVR is the family of microcontrollers that was developed by the ATMEL in the year 1996. These are the modified Harvard Architecture 8-bit RISC Single Microcontroller Chip.The above diagram above shows the basic architecture of the AVR. Where,...
and one that does not alter the interrupt status. A jump-and-link instruction will always create a return capability with the explicit interrupt posture at the point of the jump. These are exposed to C as function attributes, which means that the interrupt status is controlled via structed pr...
Once the PLC starts executing the program it will not stop until an interrupt is given. This is just a simple setup and a PLC has the ability to control much larger and more complex processes like PWM control, Sensing, etc. A PLC is usually designed in a way for the customer so ...
