The crossbars (referred to as XBAR throughout this chapter) provide flexibility to connect device inputs, outputs, and internal resources in a variety of configurations.
Figure 7-379 CONTROLSS XBAR DiagramThe real time control subsystem contains a total of eight XBARs:
Each of the XBARs is named according to signal source routed to the inputs. For example, the INPUTXBAR brings external signals "in" to the device. The OUTPUTXBAR takes internal signals "out" of the device to a GPIO. The PWMXBAR takes the signal to the trip inputs of the PWM. Similarly, the Diode Emulation logic synchronous values are routed to the Min Dead-Band logic (MDL) and Illegal Combo logic (ICL) of the PWMs via the MDLXBAR and the ICLXBAR respectively. The INTXBAR routes the large quantity of real-time CONTROLSS interrupts efficiently to the SoC interrupt controller. The DMAXBAR routes DMA requests from the real-time CONTROLSS to the SOC EDMA module. Both the INTXBAR and DMAXBAR limit the number of interrupt and DMA requests going from CONTROLSS to the SOC. The PWMSYNCOUTXBAR routes all the PWM sync outputs to SoC TIMESYNC logic and the OUTPUTXBAR.
Further details about each of these XBARs can be found in the following sections.
