Default
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.MACAWH and SU.MACAWL. Address information for read operations must be located in SU.MACRADH and
SU.MACRADL. The user must also write a 1 to the MCS bit, and the DS33Z11 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.
