Post subject:  Wiring up two CPLD's

Does anyone have an example (screen shots, etc.) that show how I can connect two CPLD's (ATF1504 and 1508) to one JTAG connector?

BTW, I'm assuming this can be done....or, do I need two JTAG connectors?

Thanks!

Here is an example from Atmel/Microchip

I believe I saw the same layout for Xilinx CPLD as well. I've never tried this though.
