Objective data sheet
8.6.2 Semi-automatic mode: manual selection of bit rate range with automatic
bandwidth and slew rate adjustment within this range
In this mode, the range of bit rates where the automatic selection of bandwidth and slew
rate is operating is limited. However, within this range of bit rates, the optimum bandwidth
and slew rate are automatically chosen.
This mode can be achieved by setting the SLEWOCT[2:0] and BWOCT[2:0] bits to the
required range of bit rates. The ACE functionality is operating but limited to this range of
bit rates.
Again, with the bits SLEW[4:0] and BW[4:0] further optimization of the relative bandwidth
and relative slew rate is possible.
