4.6.1 PSS Operating Mode Description
The resistive voltage divider connected to the PSS
pin provides the internal comparator with the

comparator with the mxV
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:

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