4.3.1.5. set_hssi_profile for F-Tile

This SAL command is used to program the profile information to the DR CSR registers and set the Trigger Reconfig bit to start the DR sequence. The DR completion status is reflected in HSSI Command/Status CSR bit [3:2] with error indication shown in bit 4. This set_hssi_profile SAL command is executed in HW and not through SAL NIOS firmware to avoid extra latency introduced in the DR sequence.

set_hssi_profile HSSI Write Data[19:15] = 1E 10GE/25GE Selection Register

sel_25g_10g [3:0]

User to set these bits to select 10GE or 25GE for the active ports in the selected profile. Bit definition as below.

1’b0 – 25GE is selected

1’b1 – 10GE is selected

Bit 0 – Select 25GE/10GE for Port 0

Bit 1 – Select 25GE/10GE for Port 1

Bit 2 – Select 25GE/10GE for Port 2

Bit 3 – Select 25GE/10GE for Port 3

Note that the port specific bits only apply to the active ports in the selected profile.

This register is applicable only to the following profiles in FGT Reconfig Groups:
  • 4x 25GE/10GE profile in 100GE-4 Group
  • 2x 25GE/10GE profile in 100GE-2 Group
  • 1x 25GE/10GE profile in 25GE-1 & 50GE-1 Group

This register is not applicable for any FHT Reconfig Groups as 10GE rate is not supported by FHT
