0012 description: |
0013 An i2c gate is useful to e.g. reduce the digital noise for RF tuners connected
0014 to the i2c bus. Gates are similar to arbitrators in that you need to perform
0015 some kind of operation to access the i2c bus past the arbitrator/gate, but
0016 there are no competing masters to consider for gates and therefore there is
0017 no arbitration happening for gates.
