MICROPROCESSOR AND MICROCONTROLLER

Detailed explanation-1: -Pin 9 − It is a RESET pin, which is used to reset the microcontroller to its initial values. Pins 10 to 17 − These pins are known as Port 3.

Detailed explanation-2: -A typical microcontroller can have between 6 and 60 pins on it, to which you’re expected to attach power connections, input and output connections, and communications connections. Every microcontroller has different configurations for its pins, and often one pin will have more than one function.

Detailed explanation-3: -A power-on reset (PoR) is a circuit that provides a predictable, regulated voltage to a microprocessor or microcontroller with the initial application of power. The PoR system ensures that the microprocessor or microcontroller will start in the same condition every time that it is powered up.
