| 31:6 | RESERVED | R | 0h | |
| 5:4 | STANDBYMODE | R/W | 2h | Configuration of the local initiator state management mode. By definition, initiator may generate read/write transaction as long as it is out of STANDBY state. 3 Smart-Standby wakeup-capable mode: local
initiator standby status depends on local
conditions, i.e. the module's functional
requirement from the initiator. IP module
may generate (master-related) wakeup events
when in standby state.Mode is only relevant
if the appropriate IP module "mwakeup"
output is implemented.
2 Smart-standby mode: local initiator standby
status depends on local conditions, i.e.
the module's functional requirement from
the initiator.IP module shall not generate
(initiator-related) wakeup events.
1 No-standby mode: local initiator is
unconditionally placed out of standby
state.Backup mode, for debug only.
0 Force-standby mode: local initiator is
unconditionally placed in standby
state.Backup mode, for debug only. |
| 3:2 | IDLEMODE | R/W | 2h | 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. 3 Smart-idle wakeup-capable mode: local
target's idle state eventually follows
(acknowledges) the system's idle requests,
depending on the IP module's internal
requirements.IP module may generate (IRQ-
or DMA-request-related) wakeup events when
in idle state.Mode is only relevant if the
appropriate IP module "swakeup" output(s)
is (are) implemented.
2 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.
1 No-idle mode: local target never enters
idle state.Backup mode, for debug only.
0 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. |
