Note 4: Hex addresses 80’ to FF’ are only available when using the eighth address bit in the HDL version of the SCANSTA111. The Silicon part has seven address
lines and will treat the most-significant address bit as a don’t care.
The SCANSTA111 supports single and multiple modes of
addressing a ’STA111. The single mode selects one ’STA111
and is called Direct Addressing. More than one ’STA111
device can be selected via the Broadcast and Multi-Cast
Addressing modes.
DIRECT ADDRESSING: The ’STA111 enters the Wait-For-
Address state when:
1.
its TAP Controller enters the Test-Logic-Reset state, or
2.
its instruction register is updated with the GOTOWAIT
instruction (while either selected or unselected).
Each ’STA111 within a scan network must be statically con-
figured with a unique address via its S
(0-6) inputs. While the
’STA111 controller is in the Wait-For-Address state, data
shifted into bits 6 through 0 of the instruction register is
compared with the address present on the S
(0-6) inputs in the
Update-IR state. If the seven (7) LSBs of the instruction
register match the address on the S
(0-6) inputs, (see Figure
6) the ’STA111 becomes selected, and is ready to receive
Level 2 Protocol (i.e., further instructions). When the
’STA111 is selected, its device identification register is in-
serted into the active scan chain.
All ’STA111s whose S
(0-6) address does not match the in-
struction register address become unselected. They will re-
main unselected until either their TAP Controller enters the
Test-Logic-Reset state, or their instruction register is up-
dated with the GOTOWAIT instruction.
BROADCAST ADDRESSING:
The Broadcast Address allows a tester to simultaneously
select all ’STA111s in a test network. This mode is useful in
testing systems which contain multiple identical boards. To
avoid bus contention between scan-path output drivers on
different boards, each ’STA111’s TDO
B buffer is always TRI-
STATEd while in Broadcast mode. In this configuration, the
on-chip Linear Feedback Shift Register (LFSR) can be used
to accumulate a test result signature for each board that can
be read back later by direct-addressing each board’s
’STA111.
MULTICAST ADDRESSING:
As a way to make the broadcast mechanism more selective,
the ’STA111 provides a Multi-cast addressing mode. A
’STA111’s multi-cast group register (MCGR) can be pro-
grammed to assign that ’STA111 to one of four (4) Multi-Cast
groups. When ’STA111s in the Wait-For-Address state are
updated with a Multi-Cast address, all ’STA111s whose
MCGR matches the Multi-Cast group will become selected.
As in Broadcast mode, TDO
B is always TRI-STATEd while in
Multi-cast mode.
