Multiplexed External Bus Interface (MEBIV3)
4.1
This section describes the functionality of the multiplexed external bus interface (MEBI) sub-block of the
S12 core platform. The functionality of the module is closely coupled with the S12 CPU and the memory
map controller (MMC) sub-blocks.

that are accessible externally. On some chips, these may not all be bonded out.
The MEBI sub-block of the core serves to provide access and/or visibility to internal core data
manipulation operations including timing reference information at the external boundary of the core and/or
system. Depending upon the system operating mode and the state of bits within the control registers of the
MEBI, the internal 16-bit read and write data operations will be represented in 8-bit or 16-bit accesses
externally. Using control information from other blocks within the system, the MEBI will determine the
appropriate type of data access to be generated.
