This section describes subsystem integration in the device, including information about clocks, resets, and hardware requests.
Figure 15-2 shows BB2D integration.
The BB2D subsystem is connected to the level 3 (L3_MAIN) interconnect by two 128-bit master interfaces and one 32-bit slave interface.
Table 15-1 through Table 15-3 summarize the integration of the subsystem in the device.

Interrupt Requests | ||||
Module Instance | Source Signal Name | Destination IRQ_CROSSBAR Input | Default Mapping | Description |
BB2D | BB2D_IRQ | IRQ_CROSSBAR_120 | MPU_IRQ_125 | BB2D interrupt request to the device interrupt crossbar |

The “Default Mapping” column in Table 15-3, BB2D Hardware Requests shows the default mapping of module IRQ source
signals. These IRQ source signals can also be mapped to other lines of each
device Interrupt controller through the IRQ_CROSSBAR module.
For more information about the IRQ_CROSSBAR
module, see IRQ_CROSSBAR Module Functional Description, in Control
Module.
For
more information about the device interrupt controllers, see Interrupt
Controllers.
No DMA and no wake-up requests are generated by the BB2D module.
