PIC18F97J60 FAMILY
18.2
The Ethernet module uses three independent memory
spaces for its operations:
• An Ethernet RAM buffer which stores packet data
• A set of 8-bit Special Function Registers (SFRs),
• A separate set of 16-bit PHY registers used

Preliminary
The Ethernet buffer and PHY control registers are
contained entirely within the Ethernet module and can-
not be accessed directly by the microcontroller. Data is
transferred between the Ethernet and microcontroller
by using buffer and pointer registers mapped in the
microcontroller’s
between the SFRs and the Ethernet module’s memory
spaces are shown in Figure 18-3.
