Coding of bit fields LEVxV in SWD Configuration Registers

After power-on the supply watch dog is preconfigured to operate in the lower voltage

range.

Coding of bit fields LEVxV in PVC Configuration Registers

The core voltages are controlled internally to the nominal value of 1.5 V; a variation of

±10 % is allowed. These operation conditions limit the possible PVC monitoring values

to the predefined reset values shown in Table 26.

LEV2V: interrupt request

2) Due to variations of the tolerance of both the Embedded Voltage Regulators (EVR) and PVC levels, this

interrupt can be triggered inadvertently, even though the core voltage is within the normal range. It is,

therefore, recommended not to use this warning level.
