2.5. Register Map

Note:
  • The register addresses listed in this section are 32-bit word address.
  • Interlaken IP core register base address is 0x2000000.
  • Design Example register base address is 0x4000000.
  • F-tile PHY register base address is 0x6000000.
  • F-tile FEC register base address is 0x8000000.
  • Access code: RO—Read Only, and RW—Read/Write.
  • System console reads the design example registers and reports the test status on the screen.

8'h54 fec_snapshot RW

This signal is only available in PAM4 mode with 32-bit soft cwbin counters enabled. fec_snapshot drives to the IP input.

Write 1 to bit[0] to snapshot CWBIN counter CSRs.

Write 0 to bit[0] to clear the collection and shadow counters.
