Bypass Register
Device Identification Register
Version
Part Number
Manufacturer ID
The Bypass Register consists of a single Shift Register stage. When the Bypass Register is
selected as path between TDI and TDO, the register is reset to 0 when leaving the Capture-DR
controller state. The Bypass Register may be used to shorten the scan chain on a system when
the other devices are to be tested.
