IDLEMODE
10b
Power management Configuration of the local target state management mode.
By definition, target can handle read/write transaction as long as it is out of IDLE state.
0x0 = Force-idle mode: local target's idle state follows (acknowledges) the system's idle requests
unconditionally, i.e. regardless of the IP module's internal requirements. Backup mode, for debug
only.
0x1 = No-idle mode: local target never enters idle state. Backup mode, for debug only.
0x2 = Smart-idle mode: local target's idle state eventually follows (acknowledges) the system's idle
requests, depending on the IP module's internal requirements. IP module shall not generate (IRQ- or
DMA-request-related) wakeup events.
0x3 = Reserved.
