NOTES:

The measurement condition is VCC = 5.0 V and Topr = 25

°C.

Refer to 10.6.4 High-Speed On-Chip Oscillator Clock for notes on high-speed on-chip oscillator clock.

The standard value shows when the HRA1 register is assumed as the value in shipping and the HRA2 register value is set to

00h.

NOTES:

The measurement condition is VCC = 2.7 to 5.5 V and Topr = 25

°C.

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

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