IDLE is a standard feature of the C28x CPU. In this mode, the CPU clock is gated while all peripheral clocks are left running. IDLE can thus be used to conserve power while a CPU is waiting for peripheral events.
Any enabled interrupt wakes up the CPU ]from IDLE mode.
To enter IDLE mode, set LPMCR.LPM to 0x0 and execute the IDLE instruction.
The CPU resumes normal operations upon any enabled interrupt event.
