2.8.4 Transmit Rise and Fall Time Adjust
The transmit output rise and fall time can be adjusted with
the two transmit rise/fall time adjust bits in the MI serial
port Channel Configuration register as shown in Table 3.
The adjustment range is -0.25 ns to +0.50 nS in 0.25 ns
steps.
Rise and Fall time Adjustment is only available in 100
Mbps operating mode.
