[ Table 12 ] Differential Output slew rate definition
NOTE : Output slew rate is verified by design and characterization, and may not be subject to production test.
[ Table 13 ] Differential Output slew rate
Description : SR : Slew Rate
Q : Query Output (like in DQ, which stands for Data-in, Query-Output)
diff : Differential Signals
For Ron = RZQ/7 setting
