Triscend's App Note AN07, "Using Keil Development Tools with Triscend FastChip and the E5 CSoC Family," warns against using PDATA; it says that it's "awkward" but doesn't explain exactly what this means. Does anyone have any experience (good or bad) in using PDATA on a Triscend E5? The App Note is at: http://www.triscend.com/products/documentation/an07.pdf
