MLI, V2.0
23.5.5 On-Chip Connections
23.5.5.1 Service Request Output Connections
Each MLI module provides eight service request outputs SR[7:0] that can be used to
generate interrupts or DMA requests. In the TC1796, four service request outputs
SR[3:0] of the MLI0 module and two service request outputs SR[1:0] of the MLI1 module
are connected to an interrupt node. Service request outputs SR[3:2] of the MLI1 module
are not connected. Four service request outputs (SR[7:4]) of each MLI module are
connected to DMA request inputs of the TC1796 DMA controller.
Each of the service request outputs used as interrupt requests are controlled by a
service request control register. The service request control registers of the MLI modules
are located inside the DMA address area. Therefore, all MLI0/MLI1 service request
control registers are named as DMA_MLIxSRCy and described in the DMA chapter
implementation part (see Page 12-107) of the TC1796 System Units User’s Manual.
All MLI service request output connections are listed in Table 23-14.
