This section details the various 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 13.14
registers can be categorized into the following sub-sections:
