Boundary Scan Register
Each Boundary Scan Register (BSR) cell has two stages. A flip-flop and a latch are used for the
serial shift stage and the parallel output stage. Table 17 lists the four BSR modes of operation.
5.10.5
Device ID Register
Table 18 lists the bits for the Device ID register. For the current version of the JEDEC continuation
characters, see the specification update for the LXT972M Transceiver.
