4.6 POWERSUPPLY SUPERVISOR DEVICE (PSS)
The Power Supply Supervisor device, described in
the Figure 31, permits supervising the crossing of
the PSS pin voltage (VPSS) through a program-
mable voltage (mxVDD/n), where n and m can be
chosen by software. This device includes:
– An internal comparator which is connected to the
internal INT line to make an interrupt request to
the Core.
– 2 resistive voltage dividers that are, respectively,
supplied by the PSS pin and the VDD pin. These
two voltage dividers are both connected to the
two inputs of the internal comparator. They con-
sist of 13 identical resistors. It is possible to se-
lect by software 5 voltage rates on the PSS
divider (nxVPSS/13) and 4 voltage rates on the
VDD divider (mxVDD/13). The n and m values can
be chosen by software. These two voltage divid-
ers are disconnected in STOP mode, and when
the PSS device is OFF.
– An internal device that allows the detection with
an hysteresis of VDD/13.
The PSS device is supplied by an internal connec-
tion to VDD supply. The following paragraphs de-
scribe the operating mode of the PSS device and
the PSS register that permits control over the PSS
device. The PSS device is switched off as soon as
the Core executes the STOP instruction, but con-
tinues to work in the WAIT mode.
