POWER SUPPLY MONITOR
As its name suggests, the power supply monitor, once enabled,
monitors the DVDD supply on the ADuC832. It indicates when
any of the supply pins drop below one of four user-selectable
voltage trip points from 2.63 V to 4.37 V. For correct operation
of the power supply monitor function, AVDD must be equal to
or greater than 2.7 V. The monitor function is controlled via
the PSMCON SFR. If enabled via the IEIP2 SFR, the monitor
interrupts the core using the PSMI bit in the PSMCON SFR.
This bit is not cleared until the failing power supply has returned
above the trip point for at least 250 ms. This monitor function
allows the user to save working registers to avoid possible data
loss due to the low supply condition, and ensures that normal
code execution does not resume until a safe supply level has
been well established. The supply monitor is also protected
against spurious glitches triggering the interrupt circuit.

CMPD
DVDD comparator bit.
This is a read-only bit and directly reflects the state of the DVDD comparator.
Read 1 indicates the DVDD supply is above its selected trip point.
Read 0 indicates the DVDD supply is below its selected trip point.
[5]
PSMI
Power supply monitor interrupt bit.
This bit is set high by the MicroConverter if CMPD is low, indicating low analog or digital supply. The PSMI bit can be
used to interrupt the processor. Once CMPD returns (and remains) high, a 250 ms counter is started. When this counter
times out, the PSMI interrupt is cleared. PSMI can also be written by the user. However, if either comparator output is
low, it is not possible for the user to clear PSMI.

TPD[1:0]
DVDD trip point selection bits. These bits select the DVDD trip point voltage as follows:

Power supply monitor enable bit. Set to 1 by the user to enable the power supply monitor circuit. Cleared to 0 by the
