For Measurement and Test Conditions, see the PCI Local Bus Specification.
3.3.7
LPC
The Local Plus Bus is the external bus interface of the MPC5121e/MPC5123. A maximum of eight configurable chip selects
(CS) are provided. There are two main modes of operation: non-MUXed and MUXED. The reference clock is the LPC CLK.
The maximum bus frequency is 83 MHz.
Definition of Acronyms and Terms:
WS = Wait State
DC = Dead Cycle
HC = Hold Cycle
DS = Data Size in Bytes
BBT = Burst Bytes per Transfer
AL = Address latch enable Length
ALT = Chip select/Address Latch Timing
tLPCck = LPC clock period
Table 22. PCI Timing Parameters1
1 See the timing measurement conditions in the PCI Local Bus Specification. It is important that all driven
signal transitions drive to their Voh or Vol level within one Tcyc.
