Each of these six registers holds one part of the Network Management Vector. The length of the Network
Management Vector is configured in the Network Management Vector Length Register (NMVLR). If
NMVLR is programmed with a value less than 12 bytes, the remaining bytes of the Network Management
Vector Registers (NMVR0–NMVR5), which are not used for the Network Management Vector
accumulating, remains 0s.
The NMVR provides accrued information over all received NMVs in the last communication cycle. All
NMVs received in one cycle are ORed into the NMVR. The NMVR is updated at the end of the
communication cycle.
