0000h
0000h
Note: The selection between Sync or Delay_Req packets is based on the corresponding
master/slave bit in the 1588 Configuration Register (1588_CONFIG).
Note: There are multiple instantiations of this register, one for each port of the LAN9312. Refer to
Section 14.2.5 for additional information.
