This section describes module integration in the device, including information about clocks, resets, and hardware requests.
Figure 24-11 shows the integration of the five HS I2C controllers in the device.
For more information about the slave idle protocol and the wake-up request, see Power Management Functional Description, in Power, Reset, and Clock Management.
Table 24-2 through Table 24-4 summarize the integration of the module in the device.

The Default Mapping column in Table 24-4
HS I2C 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 System
DMA.

module, see Enhanced DMA.
