Electronic device with temporary flag for fail safe and power cycling
First Claim
1. An electronic device, comprising:
- a flag circuit configured to generate a status flag indicating whether or not a power supply voltage to the electronic device has been cycled within about a defined time; and
a controller configured to control an operation of the electronic device and to modify an operational characteristic of the electronic device in response to the status flag indicating that the power supply voltage to the electronic device has been cycled within about the defined time.

Abstract
An electronic device includes a flag circuit configured to generate a status flag indicating whether or not a power supply voltage to the electronic device has been cycled, and a controller configured to control an operation of the electronic device and to modify an operational characteristic of the electronic device in response to the status flag indicating that the power supply voltage to the electronic device has been cycled. Methods of operating an electronic device include generating a status flag indicating whether or not a power supply voltage to the electronic device has been cycled within about a defined time, and modifying an operational characteristic of the electronic device in response to the status flag indicating that the power supply voltage to the electronic device has been cycled within about the defined time.
