Address GNMV0R=0x40, GNMV1R=0x42, GNMV2R=0x44, GNMV3R=0x46, GNMV4R=0x48, GNMV5R=0x4A,

These read-only registers hold the global network management vector. The length of the network
management vector is configured by means of the NMVLR register (see
Management Vector Length Register
The global network management vector, as presented in the communication cycle x, is the
OR-combination of all network management vectors received in the communication cycle x-1. The
controller ensures that the value read from GNMV0R is consistent.
The mapping between the receive message buffer payload bytes and the GNMVnR registers is shown in
Table

Global Network Management Vector n Register, n = [0:5] (GNMVnR)
If the NMVLR register is programmed with a value less than 12, then the
remaining bytes of the GNMVnR registers (which are not used for network
management vector accumulating) will remain 0’s.
