Thanks. I forgot about the ep9301 manual; the ep9302 manual is pretty
skimpy. We're getting one of the A/D channels run out to a mux on our
daughterboard, which will make life simpler (as soon as I figure out
how to read a muxed A/D signal.)
Anyone know how you go about reading a muxed signal? I know in
principle how a mux works but I've never tried to read one.

It's talking to the temp sensor over SPI. Turns out that the on-board
temp sensor for the ts7300 is an SPI device, which is really cool for
us - since we can measure the temp on board as well remotely with the
same chip. :-)
