26.3.2.6.6 New Data Registers (NDAT[1-4])
The four registers reflect the state of the ND flags of all configured message buffers. ND flags
corresponding to transmit buffers have no meaning. If the number of configured message buffers is less
than 128, the remaining ND flags have no meaning. The registers are reset when the communication
controller leaves CONFIG state or enters STARTUP state.
Figure 26-170 through Figure 26-173 and Table 26-153 illustrate these registers.
