Electrical and Thermal Characteristics
3.3.7
The Local Plus Bus is the external bus interface of the MPC5200. Maximum eight configurable
Chip-selects 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.
Definition of Acronyms and Terms:
WS = Wait State
DC = Dead Cycle
LB = Long Burst
DS = Data size in Byte
tPCIck = PCI clock period
tIPBIck = IPBI clock period
