26.3.2.4.12 Network Management Vector Registers (NMV[1-3])
The three network management registers hold the accrued NM vector (configurable 0-12 bytes). The
accrued NM vector is generated by the communication controller by bit-wise ORing each NM vector
received (valid frames with PPI = 1) on each channel.
The communication controller updates the NM vector at the end of each communication cycle as long as
the communication controller is either in NORMAL_ACTIVE or NORMAL_PASSIVE state.
NMVn-bytes exceeding the configured NM vector length are not valid.
Figure 26-157 illustrates these registers and Table 26-136 shows the assignment of the data bytes to the
network management vector.
