I want to use GPIF-II to interface to a device with a 4-bit parallel bus and a 5-pin JTAG. The device needs to be configured via JTAG first. Is it possible to add a JTAG state-machine into GPIF-II ? Once configured via JTAG I then want to capture date from the 4-bit parallel bus

Hi,

You can't import Verilog SM directly into the GPIF II, you have to design your own SM using GPIF II designer tool.

You can make use of maximum 256 states in one GPIF project.

For more info on GPIF designer tool see C:\Program Files (x86)\Cypress\EZ-USB FX3 SDK\1.3\doc\GPIFII_Designer\ gpif2_designer_userguide.pdf

Thanks & Regards
