Figure 22-7. Message Buffer Data Size Register (MBDSR)
This register defines the size of the message buffer data section for the two message buffer segments in a
number of two-byte entities.
The controller provides two independent segments for the individual message buffers. All individual
message buffers within one segment have to have the same size for the message buffer data section. This
size can be different for the two message buffer segments.

Field
Description
MBSEG2DS Message Buffer Segment 2 Data Size — The field defines the size of the message buffer data section in
two-byte entities for message buffers within the second message buffer segment.
MBSEG1DS Message Buffer Segment 1 Data Size — The field defines the size of the message buffer data section in
two-byte entities for message buffers within the first message buffer segment.
