Working Principle

The working principle of the MKV46F128VLH16 microcontroller is based on its architecture, which comprises of a System CPU, I/O peripherals, memories, and Power Management Circuit. The System CPU collects, processes, stores and retrieves data and instructions from memory. The I/O peripherals control the external devices connected to the microcontroller. The memories store the instructions, data and programs. Finally, the Power Management Circuit provides power to the microcontroller and ensures that it runs at the right speed and power consumption.

The System CPU has two main components, the program counter and the instruction register. The program counter stores the address of the next instruction to be executed, while the instruction register stores the instruction for execution. The instruction is decoded by the instruction decode unit and then passed on to the execution unit for execution. At the same time, the address generated by the instruction is fetched from the memory and stored in the program counter. The process is repeated until all instructions have been executed.

The I/O peripherals are used to communicate with the devices connected to the MKV46F128VLH16 microcontroller. The I/O peripherals include USART, SPI, I2C, PWM and Debug Support. These peripherals receive input from the external devices and transmit data to it. The memory contains both the program memory and data memory. The program memory stores the instructions for the microcontroller to execute, while the data memory stores the data processed by the microcontroller. Finally, the Power Management Circuit ensures that the microcontroller runs at the right voltage and power consumption.
