What are the two basic forms of reset operation?
* Answer
The two basic forms of reset operation are:
1. Power-On Reset (POR): This type of reset occurs when the power supply to a device is initially turned on. It ensures that the device starts in a known state, preventing any erratic behavior due to undefined states in the circuits. The POR circuit detects the power supply reaching a specific voltage threshold and then generates a reset signal to initialize the device.
2. Manual or External Reset: This reset is triggered manually by the user or by an external source, such as pressing a reset button or receiving a reset signal from another device. This type of reset is used to reinitialize the device or system without cycling the power. It ensures the system can recover from a fault or be reprogrammed without needing to power down.
