ADM1064
SEQUENCING ENGINE
OVERVIEW
The ADM1064 sequencing engine (SE) provides the user with
MONITOR

STATE
TIMEOUT
powerful and flexible control of sequencing. The SE implements
a state machine control of the PDO outputs, with state changes
conditional on input events. SE programs can enable complex
control of boards, including power-up and power-down sequence
control, fault event handling, and interrupt generation on warnings.
A watchdog function that verifies the continued operation of a
processor clock can be integrated into the SE program. The SE
can also be controlled via the SMBus, giving software or firmware
control of the board sequencing.
The SE state machine comprises 63 state cells. Each state has the
following attributes:
Monitors signals indicating the status of the 10 input pins, VP1
to VP4, VH, and VX1 to VX5.
Can be entered from any other state.
Three exit routes move the state machine onto a next state:
sequence detection, fault monitoring, and timeout.
Delay timers for the sequence and timeout blocks can be
programmed independently and changed with each state
change. The range of timeouts is from 0 ms to 400 ms.
Output condition of the 10 PDO pins is defined and fixed
within a state.
Transition from one state to the next is made in less than 20 μs,
which is the time needed to download a state definition
from EEPROM to the SE.

The ADM1064 offers up to 63 state definitions. The signals
monitored to indicate the status of the input pins are the
outputs of the SFDs.
WARNINGS
The SE also monitors warnings. These warnings can be generated
when the ADC readings violate their limit register value or
when the secondary voltage monitors on VPx and VH are
triggered. The warnings are OR’ed together and are available
as a single warning input to each of the three blocks that enable
exiting a state.
SMBus JUMP (UNCONDITIONAL JUMP)
The SE can be forced to advance to the next state uncondition-
ally. This enables the user to force the SE to advance. Examples
of the use of this feature include moving to a margining state or
debugging a sequence. The SMBus jump or go-to command can
be seen as another input to sequence and timeout blocks to
provide an exit from each state.
