Host MAC CSR Data
This field contains the value read from or written to the Host MAC CSR as
specified in the
(MAC_CSR_CMD). Upon a read, the value returned depends on the R/nW
bit in the MAC_CSR_CMD register. If R/nW is a 1, the data in this register
is from the Host MAC. If R/nW is 0, the data is the value that was last written
into this register.
Note:
Host MAC CSR Interface Data Register (MAC_CSR_DATA)
This read-write register is used in conjunction with the
(MAC_CSR_CMD)
Note: The full list of Host MAC CSR’s are described in
The MAC_CSR_CMD and MAC_CSR_DATA registers must not be
modified until the CSR Busy bit is cleared in the MAC_CSR_CMD
register.
