STM32L051 voltage regulator in Stop mode

[MZubk]

Hi,

Turning Voltage regulator into low-power mode (LPR) in Stop mode possible only for Category 1 devices as stated in RefMan (6.4.1 p158), but referring on datasheet for L051 family (that's category 3) that's however possible (3.1 p14 & 3.4.3 p21).

So is it possible to use that mode at category 3 devices?
