5.4 Register Structure
The device has eight 16-bit registers. A map of the registers is shown in
Section 4.2, “MI Serial Port Register Summary”
. See
Chapter 4,
Registers
for a complete description of each register.
The eight registers consist of six registers that are defined by IEEE 802.3
specifications (registers 0 to 5) and two registers that are unique to the
device (registers 17 and 18).
Table 5.1
gives a summary of the functions
of each register.
