TABLE 1. Glossary of Terms
LFSR
Linear Feedback Shift Register. When enabled, will generate a 16-bit signature of sampled serial
test data.
Local Scan Port. A four signal port that drives a “l(fā)ocal” (i.e. non-backplane) scan chain. (e.g.,
TCK
L1
, TMS
L1
, TDO
L1
, TDI
L1
)
Local is used to describe IEEE Std. 1149.1 compliant scan rings and the SCANPSC110F Bridge
Test Access Port that drives them. The term “l(fā)ocal” was adopted from the system test architecture
that the ’PSC110F Bridge will most commonly be used in; namely, a system test backplane with a
’PSC110F Bridge on each card driving up to 3 “l(fā)ocal” scan rings per card. (Each card can contain
multiple ’PSC110Fs, with 3 local scan ports per ’PSC110F.)
Park, parked, unpark, and unparked, are used to describe the state of the LSP controller and the
state of the local TAP controllers (the “l(fā)ocal TAP controllers” refers to the TAP controllers of the
scan components that make up a local scan ring). Park is also used to describe the action of
parking a LSP (transitioning into one of the Parked LSP controller states). It is important to
understand that when a LSP controller is in one of the parked states, TMS
L
is held constant,
thereby holding or “parking” the local TAP controllers in a given state.
Test Access Port as defined by IEEE Std. 1149.1
Selected and Unselected refers to the state of the ’PSC110F Bridge Selection Controller. A
selected ’PSC110F has been properly addressed and is ready to receive Level 2 protocol.
Unselected ’PSC110Fs monitor the system test backplane, but do not accept Level 2 protocol
(except for the GOTOWAIT instruction). The data registers and LSPs of unselected ’PSC110Fs are
not accessible from the system test master.
