Table 3. I/O Shift Register Order
Table 4. ispGDX Device ID Codes
The ispGDXV/VA devices provide IEEE1149.1a test
capability and ISP programming through a standard
Boundary Scan Test Access Port (TAP) interface.
The boundary scan circuitry on the ispGDXV/VA Family
operates independently of the programmed pattern. This
allows customers using boundary scan test to have full
test capability with only a single BSDL file.
The ispGDXV/VA devices are identified by the 32-bit
JTAG IDCODE register. The device ID assignments are
listed in Table 4.
The ispJTAG programming is accomplished by execut-
ing Lattice private instructions under the Boundary Scan
State Machine.
Contact Lattice Technical Support to obtain more de-
tailed programming information.
