3.5. Registers

The PTP monitor registers are part of the Packet Client block of each Ethernet IP instance. The Packet Client base address for each IP instance is available in Register Maps.
For example, the PTP monitor registers address in the third Ethernet IP instance is equivalent to 0x0210_0400, where:
  • 0x0200_0000 is the Ethernet IP: Instance 2 base address
  • 0x0010_0000 is the Packet Client base address for the specified IP instance
  • 4*0x100 is the PTP monitor base address for the specified IP instance
Table 12.  PTP Monitor RegistersAll address offsets are specified in the word address format.
