NOTES:
1.
VCC = 2.7 V to 5.5 V, Topr = -40
°C to 85°C (D, J version) / -40°C to 125°C (K version), unless otherwise specified.
2.
The standard value shows when the reset is deasserted for the FRA1 register.
NOTE:
1.
VCC = 2.7 V to 5.5 V, Topr = -40
°C to 85°C (D, J version) / -40°C to 125°C (K version), unless otherwise specified.
NOTES:
1.
The measurement condition is VCC = 2.7 to 5.5 V and Topr = -40 to 85
°C (D, J version) / -40 to 125°C (K version), unless
otherwise specified.
2.
Waiting time until the internal power supply generation circuit stabilizes during power-on.
3.
Time until CPU clock supply starts since the interrupt is acknowledged to exit stop mode.
