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 26-142 shows the assignment of the data bytes to the

network management vector.
