23.4.24 MSGVAL_X Register (offset = C0h) [reset = 0h]
MSGVAL_X is shown in Figure 23-42 and described in Table 23-37.
With the message valid X register, the CPU can detect if one or more bits in the different message valid
registers are set. Each bit of this register represents a group of eight message objects. If at least one of
the MsgVal bits of these message objects are set, the corresponding bit in the message valid X register
will be set. Example 3. Bit 0 of the message valid X register represents byte 0 of the message valid 1
register. If one or more bits in this byte are set, bit 0 of the message valid X register will be set.
