Abstract of JTAG operations
There are f our basic access to command register
and to data register. And the access is executed
based on the status shif t of TAP controller.
TAP controller is shif ted of its status by the TMS
input and make a control signal which is needed to
each state.
Capture operation
Result of the boundary scan test or the f ixed
data which is def ined to each register, is sampled.
For operation, load the input data into shif t register
stage.
Shif t operation
Through the boundary scan path, access f rom external
is done. M66290A set the data f rom external and at the
same time, output the data which is sampled by capture
operation.
For register operation, right shif t is executed among
shif t register stage of each bit.

Update operation
In shif t operation, driv e the data which is set by external.
For register operation, transf er the v alue which is set to
shif t register stage, to parallel output stage.
JTAG interf ace shif ts the internal state according to TMS
input, and do two kinds of operations as f ollows. Both are
basically
executed in turn of "Capture -> Shif t -> Update".
Set the command code into command register and when
path sequence comes, select the data register which is
the object of the operation.
DR path sequence
To selected data register, ref er or set the data.
