Note (1): These1-byte register values are merely copied by the BBT3821 from the I2C address space on Power-up or RESET, or on a periodic direct DOM update
operation (i.e. with Register bit 1.C018’h.2 Table 51 not set) under the control of Register 1.A100’h (Table 38). For further details see Table 27 in the XENPAK
MSA Rev 3.0 specification, especially Note 2. If it is desired to write this data into a DOM device through the MDIO interface, it will need to be written one byte
at a time via the methods discussed in “MDIO Register Addressing” on page 15.
