EVAL-ADM106x
The ADM106x software Sequencing Engine window provides the
facility to edit each state individually, then report the configuration
of all of the states together, so that the user can easily read the flow
of events that need to occur. The Sequencing Engine window is
shown in figure 46:-

PROGRAMMING THE PDO’S
The State editor allows the user to program each state individually.
The program flow from top to bottom of the state editor is:-
When programming a state, the user should consider what events
need to happen in the order suggested by the software. The first
thing to consider when entering a state is what should the outputs of
the ADM106x be doing. For instance, in the first state, the user may
want to wait for the ADM106x to detect that a digital input has been
asserted before anything is enabled, in which case, all of the PDO’s

fails to occur. The user can set a time limit on how long it
can take for the End-of Step to occur. If the event does not
happen, then the user can take the decision to take some
remedial action (e.g.) if a supply fails to come into
tolerance after 100ms, it is likely that there is a fault on
that supply and the user may wish to shut all supplies
down.
Monitor- While the End- of Step function focuses on a
single event, the Monitor function provides the ability to
ensure that any/all previous events are still valid (e.g.) if
the ADM106x is about to turn on supply number 6, it can
check that supplies 1-5 are still in tolerance. It does this
by simply OR’ing the status of selected blocks together. If
any one of these events fails then the Monitor function will
exit to a state that takes remedial action (e.g.) to shut off
all of the supplies.

PROGRAMMING THE SEQUENCE FUNCTION
To enable the Sequence function, click the Sequence> button.
Programming the Sequence function is formatted into an “IF
event occurs, then GOTO State X after Yms” statement. The
drop-downs force the user to configure the Sequence in a valid
format. The first drop-down box lists the events that could
progress the sequence. They are:-
1. The inputs
2. Warning
3. SMBus Jump
Use the drop down boxes to configure the Sequence for the
selected state. The configuration is automatically displayed in the
‘Sequence Engine Program’ above.

Sequence
A valid condition on these (e.g.) a supply in tolerance,
a digital input asserted- could dictate the sequence.
Warning is a signal from a wide OR gate which can
be used to dictate the sequence. The inputs to this OR
gate are:-
i.
ii.
iii.
iv.
Preliminary Technical Data
The output from the secondary detectors on
VP1-4 and VH
The status of the ADC channels on the
inputs (i.e.) whether the value read exceeds
the value set in the limit register (see section
on Read-back)
The status of the ADC channel on the
internal temp sensor and D1P/D1N
(ADM1062/3) and D2P/D2N (ADM1063
only)
The status of the ADC channels on AUX1
and AUX2 (ADM1066 only).
