Hello everyone, in this lesson we will talk about the meaning of the reset signal in the circuit

2

00:00:10,066 --> 00:00:16,466

The reset signal is also called RESET, which is one of the basic working conditions of the chip

3

00:00:17,733 --> 00:00:26,333

It is used to instruct the chip to start working again, similar to the clear key of a calculator

4

00:00:27,066 --> 00:00:35,633

When the clear key is pressed, all calculation data will disappear and start from scratch

5

00:00:37,266 --> 00:00:46,933

When the chip has a problem or crashes, a reset signal is needed to return the chip to the initial working state

6

00:00:47,933 --> 00:00:52,366

In the circuit, most reset signals are active low

7

00:00:53,533 --> 00:00:59,133

It will continue to be high when the chip is working normally

8

00:00:59,533 --> 00:01:05,133

When the chip needs to be reset, the reset signal will be pulled low

9

00:01:06,200 --> 00:01:11,633

For example, there is a dedicated reset button on the desktop host,

10

00:01:12,100 --> 00:01:14,733

which is connected to a reset signal

11

00:01:15,700 --> 00:01:20,500

When the reset button is pressed, the computer will restart

12

00:01:21,100 --> 00:01:24,200

This is what the reset signal does
