Message Buffer Header Area (MCR[FAM] = 0)
The message buffer header area contains all message buffer header fields of the physical message buffers
for all message buffer types. The following rules apply to the message buffer header fields for the three
type of message buffers.
1. The start byte address SADR_MBHF of each message buffer header field for
individual message
buffers
and
receive shadow buffers
must fulfill
.
SADR_MBHF = (i * 10) + SYMBADR[SMBA]; (0 <= i < 256)
Eqn. 22-7
2. The start byte address SADR_MBHF of each message buffer header field for the
FIFO
must fulfill
.
SADR_MBHF = (i * 10) + SYMDARD[SMBA]; (0 <= i < 1024)
