This section identifies the requirements for initializing the surrounding modules when the module must be used for the first time after a device reset. This initialization of surrounding modules is based on the integration and environment of the eMMC/SD/SDIO modules. For more information, see Section 27.3, eMMC/SD/SDIO Integration, and Section 27.2, eMMC/SD/SDIO Environment.Table 27-23 shows the global initialization of surrounding modules.
Surrounding Modules | Comments |
---|---|
PRCM | Module interface and functional clocks must be enabled. See Power, Reset, and Clock Management. |
Control module | Module-specific pad muxing and configuration must be set in the control module. See Control Module . |
DMA_CROSSBAR | DMA_CROSSBAR configuration must be done to allow module DREQs to be mapped to certain device DMA line. For more information see DMA_CROSSBAR Module Functional Description, in Control Module. |
Device DMAs | Device DMAs configuration must be done to enable the module DMA channel requests. |
IRQ_CROSSBAR | IRQ_CROSSBAR configuration must be done to allow module IRQs to be mapped to certain device INTC line. For more information see IRQ_CROSSBAR Module Functional Description, in Control Module |
Device INTCs | Device INTCs must be configured to enable the interrupt request generation. For more information see Interrupt Controllers |
