1. All monitors that are active at power-up will gate the power up recovery and prevent exit from POWERUP phase until the
minimum level is crossed. These monitors can in some cases be masked during normal device operation, but when active
will always generate a destructive reset.
2. Voltage monitors marked as non maskable are essential for device operation and hence cannot be masked.
3. There is no voltage monitoring on the VDD_HV_B and VDD_HV_C I/O segments. For applications requiring monitoring of
these segments, either connect these to VDD_HV_A at the pcb level or monitor externally.
4. LVD_FLASH is active in low power modes to ensure that VDD_HV_FLA does not drop below 2.5V, so that Flash can exit
from low power mode upon wakeup.
2.6 Supply current characteristics
Current consumption data is given in the following table. These specifications are design
targets and are subject to change per device characterization.
