Preliminary specification
Specifications in this manual are tentative and subject to change.
Figure 5.2
Time delay from Suspend Request until Erase Suspend
NOTES:
1.
The measurement condition is VCC = AVCC = 5.0V and Topr = 25
°C.
2.
Necessary time until the voltage detection circuit operates when setting to “1” again after setting the VCA26 bit in the VCA2
register to “0”.
3.
Maintain Vdet2 > Vdet1.
NOTES:
1.
The measurement condition is VCC = AVCC = 5.0V and Topr = 25
°C.
2.
Time until the voltage monitor 2 interrupt request is generated since the voltage passes Vdet1.
3.
Necessary time until the voltage detection circuit operates when setting to “1” again after setting the VCA27 bit in the VCA2
register to “0”.
4.
Maintain Vdet2 > Vdet1.
NOTES:
1.
This condition is not applicable when using with VCC
≥ 1.0V.
2.
When turning power on after the time to hold the external power below effective voltage exceeds10s, refer to Table 5.9 Reset
