Figure 5.2
Time delay from Suspend Request until Erase Suspend
NOTES:
1.
The measurement condition is VCC = AVCC = 2.7V to 5.5V and Topr = -40
°C to 85 °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.
Hold Vdet2 > Vdet1.
NOTES:
1.
The measurement condition is VCC = AVCC = 2.7V to 5.5V and Topr = -40
°C to 85 °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.
Hold Vdet2 > Vdet1.
