This section details the various LAN9313/LAN9313i switch control and status registers that reside
within the switch fabric. The switch control and status registers allow configuration of each individual
switch port, the switch engine, and buffer manager. Switch fabric related interrupts and resets are also
controlled and monitored via the switch CSRs.
The switch CSRs are not memory mapped. All switch CSRs are accessed indirectly via the
Fabric CSR Interface Command Register
Register
(SWITCH_CSR_DIRECT_DATA)
the switch CSRs must be performed through these registers. Refer to
for additional information.
Note: The flow control settings of the switch ports are configured via the
Table 13.12
