Took a look at a recent EBG datasheet and there are 16 FREGs in MMIO, however the last 4 are not contiguous with the first 12. Haven't had time to check the 300-series datasheet to see if it's the same.

Also, I noticed that newer EBG SPI programming guides now say SW sequencing is no longer supported (older versions said it *was* supported).
