The NVIC and it's registers are at least described in the Cortex M3 Technical reference:

hi.

thanks for your replay.

but still i cannot find the registers for the nvic description its all in general.

where can i find the full description for every bit in the registers?

something like this :

Bits 31:27 Reserved, always read as 0.

Bits 26:24 MCO: Microcontroller clock output

Set and cleared by software.

0xx: No clock

100: System clock (SYSCLK) selected

101: HSI clock selected

110: HSE clock selected

111: PLL clock divided by 2 selected

Note: This clock output may have some truncated cycles at startup or during MCO clock

source switching.

Bits 23:22 Reserved.

Bits 21:18 PLLMUL: PLL multiplication factor

It's in chapter 8: ''Nested Vectored Interrupt Controller'' in that document (Cortex-M3 Tech. Ref.).

You also have the

chapter 4.3. And the NVIC_Type definition in Libraries/CMSIS/CM3/CoreSupport/core_cm3.h from the firmware package.
