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,...)

No default value after reset.
