COMMAND DESCRIPTION
Each command description contains two parts: Command Parame-
ters and Command Reply. In the Command Parameters part, a figure is
used to illustrate the byte sequence of the parameters. All the parameter
descriptions are listed below the figure. In the Command Reply part,
another figure is used to illustrate the reply sequence in the reply
message. The reply description is listed below the figure. For detailed
information about the packet of command message and reply message,
refer to page 30.
Table-17 ConfigDev Command (Encoding: 01H)
This is the first command to be issued. If this command is not issued, the default value will be used.

Description
1-2
SysClk
4E20H
SysClk=Frequency of System Clock (Hz)/1000. For example, if the system clock is 20 MHz, this value
would be 20000.
Unit: sys-ticks in 1 ms (MSB first)
Note: Wrong configuration will make IMAOS’s timer work improperly.
3Tin
2H
Timer of entering failure alarm state. When a defect persists for a period set by this timer, the
IDT82V2604will enter failure alarm state.
Unit: 1 s
4Texit
0AH
Timer of exiting failure alarm state. If a defect no longer exists for a period set by this timer, the
IDT82V2604 will exit failure alarm state.
Unit: 1 s
5
No
0H
Reserved. Write 0 to this field.

TCAlpha&Delta
67H
Alpha value is the number of consecutive incorrect HEC fields for the Rx cell synchronization state
machine to exit sync state.
Delta value is the number of consecutive correct HEC fields for the Rx cell synchronization state machine
to enter sync state.
