Bit 1: MAC Command RW (MCRW) If this bit is written to 1, a read is performed from the MAC. If this bit is written
to 0, a write operation is performed. Address information for write operations must be located in
SU.MACAWL. Address information for read operations must be located in
user must also write a 1 to the MCS bit, and the DS33R11 will clear MCS when the operation is complete.
Bit 0: MAC Command Status (MCS) Setting MCS in conjunction with MCRW will initiate a read or write to the
MAC registers. Upon completion of the read or write this bit is cleared. Once a read or write command has been
initiated the host must poll this bit to see when the operation is complete.
