Message Data
This register contains the mailbox data byte pointed at the page message
object register.
After writing in the page message object register, this byte is equal to the
specified message location (in the mailbox) of the pre-defined identifier +
index. If auto-incrementation is used, at the end of the data register writing or
reading cycle, the mailbox pointer is auto-incremented. The range of the
counting is 8 with no end loop (0, 1,..., 7, 0,...)
