If the macro type is Shift or Shift with Capture then,
A. If the macro type is Shift with Capture, enable TDI
capture.
B. If the Sync Bit Support Enable bit is set, fetch sync bit
count, set the count length, set TMS_SM to the loop
bit and drive the TDO_SM high until sync bit count is
zero.
C. If the ScanBridge Support Initiate/Release bit is set,
drive the TDO_SM with pre- PAD bit (high) and while
TMS_SM remains set to the loop bit. Repeat for each
level of hierarchy.
D. If the Use Data/Instruction Header is enabled, fetch
the header length and data, set the count length, and
drive the TDO_SM with header data until the header
length is zero and while TMS_SM remains set to the
loop bit.
E. If the Compare or Mask/Compare is set, enable the
comparator.
F. Set the vector count length, and drive the TDO_SM
with vector data until the count length is one and
while TMS_SM remains set to the loop bit. In the LotF
mode if the count length is not zero and the TDO
buffer is empty, then gate TCK_SM until more data
are available in the TDO buffer. When TCK_SM is
disabled TMS_SM and TDO_SM will be driven with
their previous values.
G. If the Use Data/Instruction Trailer is enabled, fetch
the trailer length and data, set the count length, and
drive TDO_SM with trailer data until the trailer length
is one and while TMS_SM remains set to the loop
bit.
H. If the ScanBridge Support Initiate/Release bit is set:
a. If the TAP tracker is in the Shift-IR state and the
number of levels of hierarchy is greater than one,
set the count length to eight, and drive TDO_SM
with post-PAD bits (all high) until the count length
is zero for each level of hierarchy and while
TMS_SM remains set to the loop bit.
b. If the TAP tracker is in the Shift-DR state and the
number of levels of hierarchy is greater than one,
drive TDO_SM with a post-PAD bit (high) for each
level of hierarchy and while TMS_SM remains set
to the loop bit.
c. For the final level of hierarchy or if there is only
one level of hierarchy, and if the TAP tracker is in
the Shift-IR state, set the count length to eight,
and drive TDO_SM with post-PAD bits (all high)
until the count length is one and while TMS_SM
remains set to the loop bit.
I. If the Sync Bit Support Enable is set, fetch sync bit
count, set the count length, and drive the TDO_SM
high until sync bit count is one and while TMS_SM
remains set to the loop bit.
J. Set TMS_SM to the bit 8 of the TMS_SM Macro
Structure sequence and drive TDO_SM with the final
vector bit or trailer bit or post-PAD bit or sync bit.After
shifting out the final vector bit, disable the comparator
and register the comparison results.
10. If the Post-shift TCK_SM Count is not zero, then enable
TCK_SM and drive TMS_SM using the last seven bits of
the macro until the Post-shift TCK_SM Count is zero.
11. If the Sequencer is being used,
A. Decrement the sequence repeat count and return to
Step 3c if the Compare or Mask/Compare is enabled
and the results of compare is a fail.
B. Decrement the vector repeat count and return to
Step 3e if the if the Compare or Mask/Compare is
enabled and the results of compare is a pass.
C. Decrement the vector repeat count and return to
Step 3e if the Compare or Mask/ Compare is not
enabled.
12. If the Vector is being used return to the Idle state.
