1
0 1 Access an IOB
Read or write the IOB addressed with the lower ten bits of the JTAG
Instruction. Read data is placed in the twenty-bit IOB Copy Register. Write
Data for the IOB is from the IOB Data Register.
C1 C0=0 0 Read an IOB date into the Copy Register.
C1 C0=0 1 Write an IOB with data in IOB Data Register.
01
0 0
Not used.
0
1 1 Test mode only for programming
device with RapidConfigure
through JTAG
I-Cube only - internal test mode to test RapidConfigure through JTAG.
0
1 0 Crosspoint Array Write Testing,
Write one location per ShiftDR
Instruction Address=LowerLimit=A, Address Register=Upper Limit=B.
C1=1, C0=1 Connect all ports in address range
C1=1, C0=0 Connect Pattern=A[1] XOR B[1]
C1=0, C0=0 Connect Pattern=A[4]
C1=0, C0=1 Connect Pattern=NOT (A[1] XOR B[1]). Compliment address
limits, Address is complimented to test A-High Port to B-Low Port
connections. Other three patterns test opposite. The number of cycles=(Sum
of (X=1), where X=Low Limit to X=High Limit) - 1
0
0 0 Sample/Preload EXTEST
External scan tests for interconnect testing.
0
0 1 Sample/Preload EXTEST
