MC9S12DP256 — Revision 1.1
Byte Data Link Controller Module
IP Bus Interface
Figure 126 BDLC Block Diagram - IP Bus Interface
The IP Bus Interface provides the interface between the IP Bus and the
rest of the BDLC. The address space of the BDLC is continuous,
consisting of 8 bytes starting at the base address. The base address of
the module is hardware programmable as defined by the IP Bus
Specification.
The register decode map is fixed and begins at the first address of the
Module Base Address. Table 107 in Register Map shows the registers
associated with the BDLC module and their relative offset from the base
address.
