ISP JTAG daisychain

[A-Neve]

Hi,
Im ready to implement my JTAG circuit and on my proto I have the two CPLD devices with seperate JTAG headers. On the final design im wanting to daisychain the two but am unsure if the 48pro2 handles daisychained JTAG.

Could anyone please clarify this for me?

Thanks

Hello A-Neve,

Thank you for posting on our forum. You do not mention which devices we are discussing so I cannot confirm if we support them or not but in general the Dataman-48Pro2 does support JTAG chains:

I would recommend that you download the control software for the 48Pro2, which will run completly unrestricted in DEMO mode and have a look at the recommended target system schematics for ISP JTAG Chain devices.

If you have any further questions, please let me know.

Best regards,
