8/21/2023 0 Comments Datasheet arduino uno atmega328pInterrupt pins of ATmega328P are given below:Īlthough there are multiple kinds of communication systems within the devices and modules but the most common one is USART. ![]() ATmega328P gives the support of 2 interrupts within the controller which can be used to get the attention of the CPU at any instant. Most of the electrical functions required an interrupt system to operate like AC dimmer, etc. To use them as output/input or for any other function it should be defined first otherwise there won’t be any default function by all I/O pins. On top of that, each port can be used for other purposes. ![]() All these pins can be used as digital input/output. This microcontroller has three digital ports (B, C, D) such as PORTB, PORTC, and PORTD. Pin configuration Details DIGITAL INPUT/OUTPUT PINS
