JTAG and ISP Interfacing
A number of industry-established methods exist for JTAG/ISP
interfacing with CPLD’s and other integrated circuits. The Philips
PZ5128 supports the following methods:
PC Parallel Port
Workstation or PC Serial Port
Embedded Processor
Automated Test Equipment
Third party Programmers
High-End JTAG and ISP Tools
A Boundary-Scan Description Language (BSDL) description of the
PZ5128 is also available from Philips for use in test program
development. For more details on JTAG and ISP for the PZ5128,
refer to the related application note: JTAG and ISP in Philips CPLDs
