Bus Hold Time
The MLB controller can shut off MLBCLK to place MediaLB in a low-power state.
Pulse width variation is measured at 1.25 V by triggering on one edge of MLBCLK and measuring the spread on the other
edge, measured in ns peak-to-peak (pp)
The board must be designed to insure that the high-impedance bus does not leave the logic state of the final driven bit for this
time period. Therefore, coupling must be minimized while meeting the maximum capacitive load listed.
