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
the
If
(R_nW)
register.
Read/Write (R_nW)
Switch Fabric CSR Interface Data Register (SWITCH_CSR_DATA)
This read/write register is used in conjunction with the
