Mailbox
The mailbox contains all the messages received or to be transmitted. Each messages is
link to a channel. The Mailbox RAM area has 128 bytes and is mapped from 0x80 to
0xFF (see Section “Mapping”, page 26 ).
The message (or message buffer) is composed of:
1 byte of message status (only used in receiving),
n bytes of data. These data are the bytes of the DATA field of the frame with the
same organization.
The message is pointed by the Message Pointer Register of the channel, the length of
the message is given by the Message Length and Status Register of the channel. This
area is a pure RAM, it contains a random value after reset.
