NOTES:
1.
The measurement condition is V
CC
= 5.0 V and T
opr
= 25
°
C.
2.
Refer to
10.6.5 High-Speed On-Chip Oscillator Clock
for notes on high-speed on-chip oscillator clock.
3.
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:
1.
The measurement condition is V
CC
= 2.7 to 5.5 V and T
opr
= 25

C.
2.
Waiting time until the internal power supply generation circuit stabilizes during power-on.
3.
Time until CPU clock supply starts after the interrupt is acknowledged to exit stop mode.
