Note: The shift operation of the data register for the shift register stage is right-shifted, therefore, the
output from JTDO is from the LSB side. Input to JTDI starts from the value to be set in LSB side.

Finished storing setup data in the shift
register stage of the selected data register.
Setup data is set in the parallel output stage
at fall of JTCK in "Update-DR" state.
JTDI input is sampled at rise
of JTCK in "Shift-DR" state.
