hi thank you for the information. So it is really possible to implement power profile in LPC1343?? If so, can you please give an idea how to accomplish it, because as i read the user manual (UM10375), it does not include the LPC1343. Thank you
I think you misunderstood. Power profiles are ONLY present in the LPC1100L chips and the 'L' version of the LPC1313. If you want to do this yourself in the LPC1343, you will need to write your own power management code.
You could possibly write a program to read the ROM from an LPC1313 and reverse engineer some of the logic, but that's obviously a fairly significant endeavour, and there are likely to be some registers that are only available or valid on the L series chips (that won't be valid on the earlier LPC1343). Presumably there were also some HW changes to improve the power performance of these newer chips since the L series has different characteristics for things like the voltage on pins using internal pullups, etc.
The short answer is ... if you want power profiles from ROM, you need to use an 'L' series LPC1100 or LPC1313 chip.
