There are four BSCAN Interfaces which are available to connect to any BSCAN capable PL Debug module, such as MicroBlaze Debug Module (MDM). The JTAG boundary scan chain is driven from the PMC TAP through all IO in the device. The BSCAN interfaces are connected to PMC Test Access Point (TAP) controller for Debug/boundary scan purpose. CAPTURE ports provide user control and synchronization over when and how the capture register information task is requested. Only the register flip-flop and latch states can be captured.
Note: When a MicroBlaze™ with a MicroBlaze Debug Module (MDM) is added to the design, the PL BSCAN1 interface will be automatically enabled and does not need to be enabled in the CIPS IP.
