Overview

SCANSTA111 Enhanced SCAN bridge Multidrop Addressable IEEE 1149.
1 (JTAG) Port April 2004 SCANSTA111 Enhanced SCAN bridge Multidrop Addressable IEEE 1149.
1 (JTAG) Port General Description The SCANSTA111 extends the IEEE Std.
1149.
1 test bus into a multidrop test bus environment.
The advantage of a multidrop approach over a single serial scan chain is improved test throughput and the ability to remove a board from the system and retain test access to the remaining modules.
Each SCANSTA111 supports up to 3 local IEEE1149.
1 scan rings which can be accessed individually or combined serially.
Addressing is accomplished by loading the instruction register with a value matching that of the Slot in...
