I have a custom ADSP21489 board that I am using with the ICE-2000. I am looking for some guidance as there appears to be conflicting information between EE-68, the ICE 2000 manual, the ADSP-21489 datasheet and the schematics to the ADSP-21489 Ez-Board.
1) The ICE 1000/2000 manual (https://www.analog.com/media/en/dsp-documentation/evaluation-kit-manuals/ICE_emu_1000_2000_rev_manual.pdf) on page 1-7 shows pin 5 of the 14-pin ICE connector as a no connect. Yet this pin is pulled high via a 10K pull-up on the ADSP-21489 Ez-Kit. And EE-68 indicates this is the voltage sense pin. Which is it?
2) EE-68 indicates that TRST should be pulled low and the ADSP-21489 Ez-Kit has TRST pulled low. According to the ADSP-21489 datasheet (page 15), TRST has an internal pull-up (ipu). Pulling this signal low with the prescribed 4.7K resistor results in this signal floating around 1V which doesn't seem right. I've seen on the newer ADSP-2158x boards from ADI that TRST is pulled high. Which is correct on the ADSP-21489 processors?
3) Newer ADSP-2158x SHARC boards don't have EMU connected. Is this still required on the ADSP-21489?
Finally, my hardware relies on the 10-pin ICE connector. EE-68 was updated last more than 10 years ago (April, 2008), long before the 10-pin connector. Are there any specific guidelines for handling this connector on an ADSP-21489?
