Managing your supervisor

The supervisory circuit ensure that microprocessors and microcontrollers function properly. Despite the popularity of the power on reset supervisory circuit, it is sometimes unclear how to select and apply that venerable circuit. Related supervisory functions to the POR include voltage sequencing, voltage tracking, manual reset, and power-fail and low-line signals. The POR ensures that the processor begins operating at a known address by asserting the processor's reset input when the processor first receives power. .
