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
I'm not sure exactly what the aversion is. But I agree that it is error-prone for most developers. Jon
Correspondence with Triscend seems to suggest that they don't quite understand PDATA; however the following seems significant: "The Triscend part ... has a 32 bit address space which all of the system peripherals and memory reside in. Port2 is actually available to you in the CSL without impacting on the amount of memory that is addressed. To be honest I'm not sure what will happen using the Compact memory model for data access" So, does anyone have any experience of what actually happens with PDATA on a Triscend E5 device?
