Chapter 14 Register Descriptions

This section describes the various LAN9312 control and status registers (CSR’s). These registers are

broken into 5 categories. The following sections detail the functionality and accessibility of all the

LAN9312 registers within each category:

Section 14.1, "TX/RX FIFO Ports," on page 167

Section 14.2, "System Control and Status Registers," on page 168

Section 14.3, "Host MAC Control and Status Registers," on page 270

Section 14.4, "Ethernet PHY Control and Status Registers," on page 286

Section 14.5, "Switch Fabric Control and Status Registers," on page 308

Figure 14.1 contains an overall base register memory map of the LAN9312. This memory map is not

drawn to scale, and should be used for general reference only.

Note:

Not all LAN9312 registers are memory mapped or directly addressable. For details on the

accessibility of the various LAN9312 registers, refer the register sub-sections listed above.
