CPLD live firmware update

We are Using several MAX3000 CPLD devices in a JTAG series chain for programming. Is it possible to reprogram one device in the chain without interrupting the operation of other devices at all...

Thank you very much for your reply!

The question was not based on observations, but we were being very cautious that it would be OK to activate the JTAG chain and update the firmware live in one device whilst other CPLDs were live and handling data.

Based on your answer, we have done a few preliminary tests and can confirm that it seems to work without issues so far.

Again, many thanks.
