JTAG and ISP Interfacing
A number of industry-established methods exist for
JTAG/ISP interfacing with CPLDs and other integrated cir-
cuits. The CoolRunner XPLA3 family supports the following
methods:
Xilinx HW 130
PC Parallel Port
Workstation or PC Serial Port
Embedded Processor
Automated Test Equipment
Third Party Programmers
Xilinx ISP Programming Tools

Instruction
Code
Description
Enable
(ISP Shift Register)
01001
Enables the Erase, Program, and Verify commands. Using the Enable instruction
before the Erase, Program, and Verify instructions allows the user to specify the
outputs of the device using the JTAG Boundary-Scan Sample/Preload command.
Erase
(ISP Shift Register)
01010
Erases the entire EEPROM array. User can define the outputs during this
operation by using the JTAG Sample/Preload command.
Program
(ISP Shift Register)
01011
Programs the data in the ISP Shift Register into the addressed EEPROM row. The
outputs can be defined by using the JTAG Sample/Preload command.
Disable
(ISP Shift Register)
10000
Allows the user to leave ISP mode. It selects the ISP register to be directly
connected between TDO and TDI.
Verify
(ISP Shift Register)
01100
Transfers the data from the addressed row to the ISP Shift Register. The data can
then be shifted out and compared with the JEDEC file. The user can define the
outputs during this operation.
