PARAMETERSPECIFICATIONS
LFU Switchover TimeLFU switchover must complete within the idle time available. LFU switchover time represents the time for which interrupts are disabled. Idle time represents the longest interval between Interrupt Service Routines (ISRs). It will depend on system parameters such as interrupt rate and ISR CPU load
