Value is for ADD only; other sp32/sp30 signals are not applicable.
To achieve 1 ns of hold time at 66.67/83.33/100 MHZ, a minimum loading of 20 pF is required.

The following conditions must be met in order to operate the MPC8272
family devices with 133 MHz bus: single PowerQUICC II Bus mode must
be used (no external master, BCR[EBM] = 0); data bus must be in Pipeline
mode (BRx[DR] = 1); internal arbiter and memory controller must be used.
For expected load of above 40 pF, it is recommended that data and address
buses be configured to low (25 Ω) impedance (SIUMCR[HLBE0] = 1,
SIUMCR[HLBE1] = 1).
