Figure 27. ispPAC-POWR1014/A TDI/ATDI Pin Selection Diagram
Table 10 shows in truth table form the same conditions required to select either TDI or ATDI as in the logic diagram
found in Figure 27.
Table 10. ispPAC-POWR1014/A ATDI/TDI Selection Table
Please refer to the Lattice application note A
N
6068,
Programming the ispPAC-POWR1220AT8 in a JTAG Chain
Using ATDI
. The application note includes specific SVF code examples and information on the use of Lattice
design tools to verify device operation in alternate TDI mode.
VCCPROG Power Supply Pin
Because the VCCPROG pin directly powers the on-chip programming circuitry, the ispPAC-POWR1014/A device
can be programmed by applying power to the VCCPROG pin (without powering the entire chip though the VCCD
and VCCA pins). In addition, to enable the on-chip JTAG interface circuitry, power should be applied to the VCCJ
pin.
When the ispPAC-POWR1014/A is using the VCCPROG pin, its VCCD and VCCA pins can be open or pulled low.
Additionally, other than JTAG I/O pins, all digital output pins are in Hi-Z state, HVOUT pins configured as MOSFET
driver are driven low, and all other inputs are ignored.
To switch the power supply back to VCCD and VCCA pins, one should turn the VCCPROG supply and VCCJ off
before turning the regular supplies on.
User Electronic Signature
A user electronic signature (UES) feature is included in the E
2
CMOS memory of the ispPAC-POWR1014/A. This
consists of 32 bits that can be configured by the user to store unique data such as ID codes, revision numbers or
