Figure 19.2 Time delay from Suspend Request until Erase Suspend
NOTES:
1. The measurement condition is V
CC = 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 V
det2 > Vdet1.
NOTES:
1. The measurement condition is V
CC = 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 V
det1.
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 V
det2 > Vdet1.
