IDLE is a standard feature of the CPU. In this mode, the CPU is turned off while CPUx.CLOCK and all peripheral clocks are left running. IDLE can thus be used to conserve power while a CPU is waiting for peripheral events. When one CPU is in IDLE, there is no effect on the other CPU subsystem.
Any enabled interrupt wakes up the CPU from IDLE mode.
To enter IDLE mode, set LPMCR.LPM to 0x0 and execute the IDLE instruction.
