The As91l1006bu Is A One To 6-port Jtag Gateway

The AS91L1006BU is a one to 6-port JTAG gateway. It partitions a single JTAG chain into six separate chains. These separate chains CAN be optionally configured to operate as a single chain. The AS91L1006BU device is used to provide enhanced capabilities to the standard IEEE1149.1. It enables the IEEE1149.1 Interface to be used in a true Multi-Drop environment without any additional signals. This Multi-Drop capability enables the standard IEEE1149.1 Interface to be used not just for stand alone PCB (Printed Circuit Board) testing, but also for complete system testing including all PCBs within a system back plane environment. The AS91L1006BU provides the capability of partitioning the PCB, into multiple smaller IEEE1149.1 scan chains totally under software control. Partitioning the IEEE1149.1 chains on the PCB has several benefits which include easier fault diagnostics capabilities as a fault on one of the IEEE1149.1 Local Scan Ports (LSPs) does not render the PCB untestable, faster Flash programming on the PCBs, and removal of IEEE1149.1 signal loading issues.
