  14 ### Advanced
  15
  16  - SERDES - 10rx, 13tx
  17    - 4rx, 4tx for OMI(DDR4 on top of SERDES with OpenCAPI protocol)
  18    - 1rx, 1tx for ethernet
  19    - 4rx, 4tx for PCIE and other CAPI devices
  20    - 3tx for HDMI
  21  - [OpenFSI](https://openpowerfoundation.org/?resource_lib=field-replaceable-unit-fru-service-interface-fsi-openfsi-specification) instead of JTAG
