ified. Table 1-13 lists the instructions supported by the ispPAC-POWR1220AT8 JTAG Test Access Port (TAP) con-
troller:
Table 1-13. ispPAC-POWR1220AT8 TAP Instruction Table
BYPASS is one of the three required instructions. It selects the Bypass Register to be connected between TDI and
TDO and allows serial data to be transferred through the device without affecting the operation of the ispPAC-
POWR1220AT8. The IEEE 1149.1 standard defines the bit code of this instruction to be all ones (11111111).
The required SAMPLE/PRELOAD instruction dictates the Boundary-Scan Register be connected between TDI
and TDO. The ispPAC-POWR1220AT8 has no boundary scan register, so for compatibility it defaults to the
BYPASS mode whenever this instruction is received. The bit code for this instruction is defined by Lattice as shown
in Table 1-13.
The EXTEST (external test) instruction is required and would normally place the device into an external boundary
test mode while also enabling the boundary scan register to be connected between TDI and TDO. Again, since the
