23.4.18 NWDAT78 Register (offset = A8h) [reset = 0h]
NWDAT78 is shown in Figure 23-36 and described in Table 23-31.
These registers hold the NewDat bits of the implemented message objects. By reading out these bits, the
CPU can check for new data in the message objects. The NewDat bit of a specific message object can be
set/reset by the CPU via the IF1/IF2 interface register sets, or by the message handler after reception of a
data frame or after a successful transmission.
