Register Name:
Register Description:
Register Address:
06Bh:
Default
Bits 0 – 7: MAC Write Address (MACAW8-15) - High byte of the MAC address. Used only for write operations.
Register Name:
Register Description:
Register Address:
06Ch:
Default
Bit 1: MAC Command RW – 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.MAC1AWH and
SU.MAC1AWL. Address information for read operations must be located in SU.MAC1RADH and SU.MAC1RADL.
The user must also write a 1 to the MCS bit, and the device will clear MCS when the operation is complete.
Bit 0: MAC Command Status – 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.
