23.4.14 NWDAT_X Register (offset = 98h) [reset = 0h]
NWDAT_X is shown in
and described in
.
With the new data X register, the CPU can detect if one or more bits in the different new data registers are
set. Each register bit represents a group of eight message objects. If at least on of the NewDat bits of
these message objects are set, the corresponding bit in the new data X register will be set. Example 1. Bit
0 of the new data X register represents byte 0 of the new data 1 register. If one or more bits in this byte
are set, bit 0 of the new data X register will be set.
