DYNAMIC ELECTRICAL CHARACTERISTICS (continued)
Characteristics noted under conditions 4.5 V ≤ V_DD ≤ 5.5 V, 6.0 V ≤ V_PWR ≤ 27 V, -40°C ≤ T_J ≤ 150°C unless otherwise noted. Typical
values noted reflect the approximate parameter mean at T_A = 25°C under nominal conditions unless otherwise noted.

Notes
27. Time necessary for the CSNS to be with ±5% of the targeted value.
28. Watchdog timeout delay measured from the rising edge of WAKE or 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_WDTO is consistent for all configured watchdog
timeouts.
