10.6 Switch Fabric Interface Logic Registers
This section details the directly addressable System CSRs which are related to the Switch Fabric.
The flow control of all three ports of the Switch Fabric can be configured via the System CSR’s Port 1 Manual Flow Con-
trol Register (MANUAL_FC_1), Port 2 Manual Flow Control Register (MANUAL_FC_2) and Port 0 Manual Flow Control
Register (MANUAL_FC_0).
The MAC address used by the switch for Pause frames is configured via the Switch Fabric MAC Address High Register
(SWITCH_MAC_ADDRH) and the Switch Fabric MAC Address Low Register (SWITCH_MAC_ADDRL).
The Switch Fabric CSR Interface Command Register (SWITCH_CSR_CMD), the Switch Fabric CSR Interface Data
Register (SWITCH_CSR_DATA) and the Switch Fabric CSR Interface Direct Data Registers (SWITCH_CSR_DI-
RECT_DATA) serve as an accessible interface to the full range of otherwise inaccessible switch control and status reg-
isters. A list of all the Switch Fabric CSRs can be seen in Table 10-9. For detailed descriptions of the Switch Fabric CSRs
that are accessible via these interface registers, refer to Section 10.7, "Switch Fabric Control and Status Registers". For
an overview of the entire directly addressable register map, refer to Section 5.0, "Register Map," on page 41.
