2. Minimum times are measured at the package pin with the load circuit, and maximum times are measured with the load circuit
3. REQ# and GNT# are point-to-point signals and have different input setup times than do bused signals. GNT# and REQ# have
4. See the timing measurement conditions in the PCI Local Bus Specification.
For Measurement and Test Conditions, see the PCI Local Bus Specification.
1.3.8
The Local Plus Bus is the external bus interface of the MPC5200B. A maximum of eight configurable chip selects (CS) are
provided. There are two main modes of operation: non-MUXed (Legacy and Burst) and MUXED. The reference clock is the
PCI CLK. The maximum bus frequency is 66 MHz.
