Switch CSR Data (CSR_DATA)
This field contains the value read from or written to the Switch Fabric CSR.
The Switch Fabric CSR is selected via the
bits of the
(SWITCH_CSR_CMD).
Upon a read, the value returned depends on the R/nW bit in the
Fabric CSR Interface Command Register
set, the data is from the switch fabric. If R/nW is cleared, the data is the
value that was last written into this register.
Switch Fabric CSR Interface Data Register (SWITCH_CSR_DATA)
This read/write register is used in conjunction with the
(SWITCH_CSR_CMD)
Section 14.5, "Switch Fabric Control and Status Registers," on page 309
indirectly accessible via this register.
Switch Fabric CSR Interface Command Register
