Table-55 DeviceInitial Command (Encoding: 01H)
This is the first command to be issued. If this command is not issued, the default value will be used.
Command Parameters
Byte Sequence
Parameter Name
Default
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_Slave’s timer work improperly.
3Tin
2H
Timer of entering failure alarm state. When a defect persists for a period set by this timer, the
IDT82V2616will enter failure alarm state.
Unit: 250 ms
4Texit
0AH
Timer of exiting failure alarm state. If a defect no longer exists for a period set by this timer, the
IDT82V2616 will exit failure alarm state.
Unit: 250 ms
5
No
0H
Reserved. Write 0 to this field.
6
TCWorkMode
7H
7
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.
8
TCLCD_Threshold
68H
0~255
LCD threshold. If the OCD anomaly persists for the time set by this parameter, LCD defect will be
reported.
Unit: one cell’s transmission time
