This section describes module integration in the device, including information about clocks, resets, and hardware requests.
Figure 17-57 shows GPMC integration.
Table 17-418, Table 17-419 and Table 17-420 summarize the integration of the module in the device.
Module Instance | Attributes | ||
Power Domain | Wake-Up Capability | Interconnect | |

The “Default Mapping” column in Table 17-420GPMC Hardware Requests shows the default mapping of module IRQ and
DREQ source signals. These module IRQ and DREQ source signals can also be mapped
to other lines of each device Interrupt or DMA controller through the
IRQ_CROSSBAR and DMA_CROSSBAR modules, respectively.
For more information about the IRQ_CROSSBAR module, see IRQ_CROSSBAR
Module Functional Description, in Control Module.
For more information about the DMA_CROSSBAR
module, see DMA_CROSSBAR Module Functional Description, in Control
Module.
For more information about the
device interrupt controllers, see Interrupt Controllers.
For more information about the device DMA_SYSTEM module, see Section 18.1, System DMA.
For more
information about the device EDMA module, see Section 18.2, Enhanced DMA.
For the description of the interrupt source, see Section 17.4.4.5, GPMC Interrupt Requests.
