POP POP_TEMP POP_INT0 lines

Is there any information available on how to use the POP_TEMP, POP_INT0, POP_INT1 from the POP memory devices?

I assume the POP_TEMP might have something to do with temperature? Protocol?

These signals are feed through pins, meaning it is essentially a wire connection from the pad on the top of the OMAP35xx device to the corresponding ball on the bottom.  Therefore, the functionality and protocol is defined by the memory vendor.

I recently came across some Micron datasheets at the Micron BeagleBoard page that can give you some idea how these are hooked up, it looks like POP_TEMP is a signal that asserts if the PoP's junction temperature goes over 85C, for the INT lines it looks like one is a NC (AC9) on the PoP and the other (AB9) goes to a LOCK signal on the PoP, these signals are described in the datasheet at http://download.micron.com/pdf/datasheets/mcp/168ball_nand_lpdram_j4xx_omap.pdf which looks to be the type which you would find on our current eval board offerings such as the Mistral EVM or BeagleBoard. I am not sure if these are currently used by the software stack or not.

thank you, exactally what I was looking for.
