NOTE:

1. The measurement condition is Topr =

−20 to 85°C (N version) / −40 to 85°C (D version), unless otherwise specified.

NOTES:

1. The measurement condition is Topr =

−20 to 85°C (N version) / −40 to 85°C (D version), unless otherwise specified.

2. These standard values show when the HRA1 register is set to the value before shipment and the HRA2 register is set to 00h.

3. These standard values show when the correction value in the FRA6 register is written into the HRA1 register.

NOTE:

1. VCC = 2.2 to 5.5 V, Topr =

−20 to 85°C (N version) / −40 to 85°C (D version), unless otherwise specified.

NOTES:

1. The measurement condition is VCC = 2.2 to 5.5 V and Topr = 25

°C.

2. Waiting time until the internal power supply generation circuit stabilizes during power-on.

3. Time until system clock supply starts after the interrupt is acknowledged to exit stop mode.
