This section describes module integration in the device, including information about clocks, resets, and hardware requests.
Figure 15-57 shows GPMC integration.
Table 15-416, Table 15-417 and Table 15-418 summarize the integration of the module in the device.

The “Default Mapping” column in Table 15-418GPMC 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 16.1, System DMA.
For more
information about the device EDMA module, see Section 16.2, Enhanced DMA.
For the description of the interrupt source, see Section 15.4.4.5, GPMC Interrupt Requests.
