4.6.1 PSS Operating Mode Description
The resistive voltage divider connected to the PSS
pin provides the internal comparator with the
nxV
PSS
/13 voltage. The resistive voltage divider
connected to the V
DD
pin provides the internal
comparator with the mxV
DD
/13 voltage. The n and
m values are selected with the PSS register. It
must be observed that the n and m values must be
selected, taking into consideration the following
electrical constraints:
0.5V < nxV
PSS
/13 at detection < V
DD
-2V
0.5V < mxV
DD
/13 at detection < V
DD
-2V
we must also have:

The PIF bit is the interrupt request flag of the PSS
device. This bit follows PSS comparator output.
