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). The BBT3821 takes no action as
a result of the values copied.
DOM Enable’ bit (Register bit 1.C018’h.2 Table 51) is not set, a four-lane external DOM device is expected to determine the values for these registers,
according to Section 11.3 in the XENPAK MSA Rev 3.0 specification. A single one-lane DOM device system will provide the values from the single DOM
device here. If the ‘Indirect DOM Enable’ bit is set, the values from the “Representative” (as set by Register bits 1.C018’h.1:0 in Table 51) lane DOM are
entered here. See “DOM Registers” on page 16. These bits are gated with the enable bits in 1.9006:7 (Table 30 & Table 31) and the LX4/CX4 select
LX4_MODE pin to drive bits 1.9004.1 & 1.9003.1 (Table 28 & Table 27), and if enabled via 1.9002 & 1.9001 (Table 25 & Table 24) to drive the LASI pin.
