Abstract
Various implementations described herein are directed to a device having alarm circuitry that receives a clock signal and provides alarm chain signals based on the clock signal. The device may include delay chain circuitry that receives the alarm chain signals from the alarm circuitry and provides delay chain signals. The device may include output circuitry that receives the delay chain signals from the delay chain circuitry and provides an alarm control signal based on the delay chain signals.
