Register Definitions
The LXT9785/LXT9785E register set includes multiple 16-bit registers, 18 registers per port.
Table 82
through
individual registers and
provides a consolidated memory map of all registers.
Base registers (0 through 8) are defined in accordance with the “Reconciliation Sublayer and
Media Independent Interface” and “Physical Layer Link Signaling for 10/100 Mbps Auto-
Negotiation” sections of the IEEE 802.3 standard.
Additional registers (16 through 21, 25, 27, and 29) are defined in accordance with the IEEE 802.3
standard for adding unique chip functions.
The BGA15 package on some registers has different default values. Some LXT9785 features are
not available on the BGA15 package. These differences are called out in the register description
and in the table notes in individual register tables.
