It runs instructions from its flash memory based on inputs provided by its various periphery. These instructions are interpreted by the onboard CPU. The results are sent to the output peripherals such as the LCD, ADC, I2C, and SPI.

The speed of execution is controlled by the frequency of the Internal Ambric Frequency Clock. This clock is divided by an internal prescaling circuit to obtain the frequency of the Instruction Clock. The Instruction Clock is further divided by an internal instruction rate correction register to calculate the instruction rate of the microcontroller. This number determines the instructions that can be processed per second.

In addition, the microcontroller can also perform two separate tasks simultaneously. This is known as multitasking and allows for complex algorithms and functions to be executed in a much shorter time. The memory and peripherals on the microcontroller can also be manipulated by the specific instructions set by the programming language used.
