Level 1 Protocol
(Continued)
Level 2 Protocol
Once the SCANPSC110F Bridge has been successfully ad-
dressed and selected, its internal registers may be accessed
via Level-2 Protocol. Level-2 Protocol is compliant to IEEE
Std. 1149.1 TAP protocol with one exception: if the
’PSC110F is selected via the Broadcast or Multi-Cast ad-
dress, TDO
will always be TRI-STATED. (The TDO
buffer
must be implemented this way to prevent bus contention.)
Upon being selected, (i.e., the ’PSC110F Selection controller
transitions from the Wait-For-Address state to one of the Se-
lected states), each of the local scan ports (LSP
, LSP
2
,
LSP
) remains parked in one of the following four TAP Con-
troller states: Test-Logic-Reset, Run-Test/Idle, Pause-DR or
Pause-IR and the active scan chain will consist of: TDI
B
through the instruction register (or the IDCODE register) and
out through TDO
B
.

The UNPARK instruction (described later) is used to insert
one or more local scan ports into the active scan chain.
Table 4 describes which local ports are inserted into the
chain, and in what order.
LEVEL 2 INSTRUCTION TYPES
There are two types of instructions (reference Table 5):
