Answer to Question #160124 in Software Engineering for RIHAD

Question

(a) Write about Oscillator and watchdog timer in ATmega32 microcontroller.

(b) What are the major differences between a microprocessor and a microcontroller?

Answer 1

a)

1) The main function of the watchdog timer is to protect the device from failures. Thanks to the watchdog timer, you can interrupt the execution of a looped program.

2) The Oscillator generates time intervals of the specified duration

b) Microcontroller - (hereinafter referred to as MC) is a chip designed for software control of electronic circuits. MC is performed on a single chip.

With the microprocessor (hereinafter MP), things are a little different. It contains an arithmetic logic unit, a synchronization and control unit, a storage device, registers, and a bus. That is, the MP contains only what is directly needed to perform arithmetic and logical operations.
