Table 4-5. ispPAC-POWR607 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-
POWR607. 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-POWR607 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 4-5.
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
ispPAC-POWR607 has no boundary scan logic, the device is put in the BYPASS mode to ensure specification com-
patibility. The bit code of this instruction is defined by the 1149.1 standard to be all zeros (00000000).
The optional IDCODE (identification code) instruction is incorporated in the ispPAC-POWR607 and leaves it in its
functional mode when executed. It selects the Device Identification Register to be connected between TDI and
TDO. The Identification Register is a 32-bit shift register containing information regarding the IC manufacturer,
device type and version code (Figure 4-19). Access to the Identification Register is immediately available, via a
TAP data scan operation, after power-up of the device, or by issuing a Test-Logic-Reset instruction. The bit code for
this instruction is defined by Lattice as shown in Table 4-5.
