Note 10:
Mode Register
1
is only available in the HDL version (up to eight LSPs). The Silicon version has three LSPs and uses Mode Register
0
only.
Note 11:
In a device with 8 LSPs there are 2
8
possible LSPN configurations: No LSPs, each individual LSP, combinations of 2 to 7 LSPs, and all 8 LSPs.

Bit 3 is normally set to logic 0 so that TCK
is free-running
when the local scan ports are parked in the
Parked-RTI
,
Parked-Pause-DR
or
Parked-Pause-IR
state. When the local
ports are parked, bit 3 can be programmed with logic 1,
forcing all of the LSP TCK
’s to stop. This feature can be
used in power sensitive applications to reduce the power
consumed by the test circuitry in parts of the system that are
not under test. When in the
Parked-TLR
state, TCK
is gated
(stopped) after 512 clock pulses have been received on
TCK
B
independent of the bit 3 value.
Bit 7 is a status bit for the TCK counter. Bit 7 is only set (logic
1) when the TCK counter is on and has reached terminal
