Overview
SCANPSC110F SCAN Bridge October 1999 SCANPSC110F SCAN Bridge Hierarchical and Multidrop Addressable JTAG Port (IEEE1149.
1 System Test Support) General Description The SCANPSC110F Bridge extends the IEEE Std.
1149.
1 test bus into a multidrop test bus environment.
The advantage of a hierarchical 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 SCANPSC110F Bridge supports up to 3 local 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 inputs.
