Today's Cypress MCUs are used in multi-power systems. There are power shutdowns which sometimes are intended and sometimes unintended, and glitches. Systems use external monitors as well as internal low-voltage detection (LVD) features of the MCU to detect power glitches and recover safely. In this app note, scenarios where a power supply falls below the LVD threshold and then recovers safely are covered.
