Overview of SCANPSC110F Bridge
Functions
(Continued)
ample, a local port which is presently in the Parked-RTIstate
does not become unparked (i.e., enter the Unparked state)
until the ’PSC110F receives an UNPARK instruction
and
the
’PSC110F’s TAP state-machine enters the Run-Test/Idle
state.
Similarly, certain transitions of the scan port-configuration
state-machine
can
force
the
state-machine into specific states. For example, when a lo-
cal port is in the Unparked state and the ’PSC110F receives
a PARKRTI instruction, the Local Port controller enters the
Parked-RTI state in which TMS
Ln
will be held low until the
port is later unparked. While TMS
is held low, all devices
on that local scan chain remain in their current TAP State
(the RTI TAP controller state in this example).
The ’PSC110F’s scan port-configuration state-machine
implements part of the ’PSC110F’s Level-2 protocol. In addi-
tion, the ’PSC110F provides a number of Level-2 instructions
for functions other than local scan port confguration. These
instructions provide access to and control of various regis-
ters within the ’PSC110F. This set instructions includes:
’PSC110F’s
TAP-control
BYPASS
EXTEST
SAMPLE/PRELOAD
IDCODE
MODESEL
MCGRSEL
LFSRSEL
Figure 5 illustrates how the ’PSC110F’s state-machines in-
teract. The ’PSC110F-selection state-machine enables or
disables
operation
of
the
state-machines. In ’PSC110Fs which are selected via
Level-1 protocol (either as individual ’PSC110Fs or as mem-
bers of broadcast or multi-cast groups), Level-2 protocol
commands can be used to park or unpark local scan ports.
Note
that
most
transitions
state-machines are gated by particular states of the
’PSC110F’s TAP-control state-machine, as shown in Figures
