Hi,
I'm working on TMS320F2812 DSP from TI. This DSP supports three power down modes - 1. Idle Mode, 2. Standby Mode, 3. Halt Mode.
The documentation says that after CPU executes "IDLE" instruction, it will immediately go to power-down mode according to the configuration.
But even if I've disabled all interrupts and executing the IDLE instruction which is as follows -
asm(" Idle");
the DSP is not going to power-down mode.

I don't know whether the assembly instruction is right or not. Please suggest if you have any information about this.

Thanks,
Vhn
