26.3.2.6.7 Message Buffer Status Changed Registers (MBSC[1-4])
The four registers reflect the state of the MBC flags of all configured message buffers. If the number of
configured message buffers is less than 128, the remaining MBC flags have no meaning.
Figure 26-174 through Figure 26-177 and Table 26-148 illustrate these registers.

Bit Field Value Description
127-0 MBS[n] Message buffer status changed.
0 A flag is reset when the header section of the corresponding message buffer is reconfigured or when it
has been transferred to the Output Buffer.
1 The flag is set whenever the Message Handler changes one of the status flags VFRA, VFRB, SEOA,
SEOB, CEOA, CEOB, SVOA, SVOB, TCIA, TCIB, ESA, ESB, MLST, FTA, FTB in the header section
(see Message Buffer Status (MBS)) of the respective message buffer.
