EVE IDLE protocol is associated with the EVE OCP target port. The configuration of the IDLE state is done by setting the EVE_SYSCONFIG[3:2] IDLEMODE bit field.
When the EVE subsystem is configured in Smart-Idle or in Smart-Idle-Wakeup, the following sequence must be performed upon an IDLE request from the PRCM:
Externally generated OCP requests (through DMA OCP target bus) to EVE memory space are gated only after the MStandby state is entered. This is required because explicit messaging with either the MPU or the DMA may be necessary before ARP32 software can reach a state that allows entrance to MStandby.
