Time necessary for the CSNS to be within ±5% of the targeted value.
Watchdog timeout delay measured from the rising edge of WAKE to RST from a sleep state condition to output turn-ON with the output
driven OFF and FSI floating. The values shown are for WDR setting of [00]. The accuracy of t
watchdog timeouts.
