AS91L1006BU
MODE_SELECT Register
The Mode_Select register allows the LSP
of the AS91L1006BU to be connected in various
different configurations. A LSP is selected for
connection within the scan chain by the contents of
the Mode_Select register.
If the LSP is not parked in a stable state,
i.e.: Pause-DR, Pause-IR, Run-Test-Idle or Test-
Logic-Reset, it will be connected into the active
scan chain. If all LSPs are parked in a stable
state, then the AS91L1006BU will perform a
bypass of the 6-LSP chain section. In this way if
both sections are in the bypass mode then the
AS91L1006BU is performing a loopback of TDI-
>Register->TDO to the host device.

X
= Don’t care
Register
= AS91L1006BU device instruction register or any of the AS91L1006BU device test
data registers.
PAD
= Insertion of a 1-bit register for data synchronization.
Upon entering Test-Logic-Reset, the register bits will be loaded with “0000000”.
