The MB91248SZPFV-GS-171K5E1 microcontroller works on the basis of two main processes, namely microcontroller tasks and interrupts.

The microcontroller tasks or higher-level software controls the process and the MCU performs a set of operations based on the task. The microcontroller receives data from external signals and programs them as one or more tasks in memory. These tasks are performed in sequence as long as the signal stays present.

Interrupts are required when external hardware signals cause changes in the workings of the microcontroller. The microcontroller momentarily interrupts the currently running task and executes the interrupt code corresponding to the signal. The signal either needs to be acknowledged or the MCU needs to be reset in order to continue the normal functioning of the program.

The MB91248SZPFV-GS-171K5E1 microcontroller is equipped with an efficient operating system and provides a reliable backup system. This helps to maintain the performance and stability of the system. It is also one of the most power-efficient microcontrollers on the market, which makes it a suitable choice for applications that are sensitive to power consumption.
