Notes

24.

Time necessary for the CSNS to be within ±5% of the targeted value.

25.

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 tWDTO is consistent for all configured watchdog timeouts.

26.

RST

low duration measured with outputs enabled and going to OFF or disabled condition.
