nap
Nap
Enters Nap power-saving mode (Supervisor only).
Details
The TARGET instruction 'nap' places the thread into a low-power state (power-saving level 0) where it does not execute instructions and consumes less power than in active mode. The instruction alters the Machine State Register (MSR) to reflect this change.
Pseudocode Operation
// Enters Nap power-saving mode (Supervisor only)Programming Note
The nap instruction is useful for reducing power consumption when a thread has no immediate work to do. It places the thread into a low-power state, but it must be used carefully as it does not execute instructions and can lead to performance degradation if overused. Ensure that interrupts are enabled before using nap to allow the system to wake up properly.
