The 2.0B spec has a typo, I believe. Section 13.3.3 says "remain dedicated to the OSPM for ~1 microsecond" when I believe it should be "~1 millisecond". (See "Total Burst Time" which is correct I believe). 2. The last sentence of 13.2.1 conflicts with 13.3.3. 13.2.1 says that burst mode prevents the overhead of SCIs. However, 13.3.3 says that while in burst mode, the EC continues to generate SCIs as normal. Which is it? 3. The description of disabling burst mode (13.3.3) says the same thing twice. The last two sentences both say the EC clears the burst enable bit. I think the last sentence should be removed. 4. I was looking at different implementations of EcSpaceHandler(). Ours in FreeBSD can handle any width divisible by 8 (8,16,32). Linux handles widths == 8. Since the EC space is 256 8 bit bytes, is multi-byte access required? Thoughts on if it will ever be?
