My GUID
These registers contain the factory-programmed read-only GUID address.
This address is unique for each module and is used by all packet types as
a unique origination address.
Figure 65 shows the GUID Registers.
Release Number - NV Address = 0x78
This register contains a hard-coded release number corresponding to a
firmware version and hardware platform. Figure 66 shows examples of the
commands and Figure 67 lists current releases to date.

As an example, if regAUTADD is set to 0x0F (Any Auto Address) and a
GUID packet is received from another module, then regAUTADD reads
back as 0x4F. The lower 4 bits indicate that the module is set to any auto
address (0xF). The upper 4 bits indicate that the packet that was just
received was a GUID Network Mode packet (0x4).
Figure 63 summarizes the configuration values for the lower 4 bits of the
register.
Figure 64 shows the Network Mode values that the module writes to the
upper 4 bits after successfully receiving a packet.
