5 0 Register Descriptions
5 2 NIC CORE REGISTERS
All registers are 8-bit wide and mapped into two pages which are selected in the Command Register (PS0 PS1) Pins RA0– RA3
are used to address registers within each page Page 0 registers are those registers which are commonly accessed during
DP83907 operation while page 1 registers are used primarily for initialization The registers are partitioned to avoid having to
perform two write read cycles to access commonly used registers
