Hello all, I have to disable the SPI,SCI, ACMP, Modular Timer, Inter Integrated Circuits in My application for pow power consumption. please anyone tell me how to disable the modules which are not required for my application. and also tell me how to implement the STOP3 mode.

Hello Shiva,

The register settings that are present following POR will generally disable the various modules. If you wish to explicitly disable the modules within you code, look in the datasheet for the reset or POR values applicable to each control register.

You do not say which MCU part you are using. The code you are using to enter stop 3 mode, and the RTI setup code would also assist.
