Times are specified with loads of 1.35 k pull-up resistance and 57 pF load capacitance on the B-side, and 167
and 57 pF load capacitance on the A-side. Different load resistance and capacitance will alter the RC time constant, thereby changing
the propagation delay and transition times.
Pull-up voltages are V

The proportional delay data from A-side to B-side is measured at 0.3V
The enable pin, EN, should only change state when the global bus and the repeater port are in an idle state.
