DV
DD
Comparator Bit.
This is a read-only bit and directly reflects the state of the DV
DD
comparator.
Read “1” indicates the DV
DD
supply is above its selected trip point.
Read “0” indicates the DV
DD
supply is below its selected trip point.
Power Supply Monitor Interrupt Bit.
This bit will be set high by the MicroConverter if either CMPA or CMPD is low, indicating low analog
or digital supply. The PSMI bit can be used to interrupt the processor. Once CMPD and/or CMPA
return (and remain) 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.

These bits select the DV

POWER SUPPLY MONITOR
As its name suggests, the Power Supply Monitor, once enabled,
monitors the DV
DD
supply on the ADuC831. It will indicate
when any of the supply pins drops below one of four user-
selectable voltage trip points, from 4.63 V to 4.39 V. For
correct operation of the Power Supply Monitor function, AV
DD
must be equal to or greater than 2.7 V. Monitor function is
controlled via the PSMCON SFR. If enabled via the IEIP2 SFR,
the monitor will interrupt the core using the PSMI bit in the
PSMCON SFR. This bit will not be cleared until the failing power
supply has returned above the trip point for at least 250ms. This
monitor function allows the user to save working registers to
avoid possible data loss due to the low supply condition, and also
ensures that normal code execution will not resume until a safe
supply level has been well established. The supply monitor is also
protected against spurious glitches triggering the interrupt circuit.
