Table 1. Pin Descriptions
(continued)
* I = input, O = output, Iu = input with pull-up, Id = input with pull-down, Ou = output with pull-up.
See Table 2.
Table 2. Equalizer Control
Other bit combinations represent test modes not to be used for normal operation.
* Use maximum loss figures for other cable types.
