Dear & Respected,

I am completely new to LPC, NXP and Cortext M0. I searched the internet a million times for any Instruction Set for Programming for the LPC Eval Boards. I have not found much information about it. Are there any Books or any Links available from where i could get the correct Instruction Set and Syntax for Cortex M0 Embedded C programming.

I have a LPC1115 Rev A Eval Board.

Thank You

Have a look at this book:
http://www.amazon.com/The-Definitive-Guide-ARM-Cortex-M0/dp/0123854776/ref=sr_1_1?ie=UTF8&qid=1409482733&sr=8-1&keywords=0123854776

Download the User Manual of the LPC1115:
http://www.nxp.com/documents/user_manual/UM10398.pdf
Have a look at chapter 28 and especially chapter 28.5

Or here:

Do you really want to develop in assembler? You can also develop in C.

Thank You Very Much. I intend to develop in C, but for C also i could not find much of the information, especially the syntax for C.

If you're looking for any Cortex-M instruction set, it's a good idea to go to the ARM Information Center.

Example; click...

  Cortex-M series processors >
    Cortex-M0 >
      Revision: r0p0 >
        Cortex-M0 Devices Generic User Guide >
          The Cortex-M0 Instruction Set

If you're searching for instruction timing, click...

  Cortex-M series processors >
    Cortex-M0 >
      Revision: r0p0 >
        Cortex-M0 Technical Reference Manual >
          Programmers Model >
            Instruction set summary

If you meet someone over there, it's probably me...

The C compiler is the GNU C compiler - there's loads of documentation on the internet.

Another book I'd recommend is "ARM Assembly Language" by William Hohl (ISBN 978-81-89643-04-1), though it will tend to whet your appetite for those 32-bit instructions that you can't have on the Cortex-M0.

If you've programmed the Atmel ATTINY and ATMEGA devices, then the Thumb instruction set on the Cortex-M0 should come naturally (with the same quirks about some instructions that work with the "high" registers and some that don't) - and it's marvellous to be freed from the constrains of 8-bit arithmetic.
