Bit Field Type Reset Description
31-6 Reserved R 0h
5-4 standbymode R/W 0h 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
0: Force-standby mode: local initiator is unconditionally placed in
standby state
Backup mode, for debug only
1: No-standby mode: local initiator is unconditionally placed out of
standby state
Backup mode, for debug only
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
3: Reserved
3-2 idlemode R/W 0h 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
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
1: No-idle mode: local target never enters idle state
Backup mode, for debug only
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
3: Reserved
1-0 Reserved R/W 0h
