6.2.1. F-Tile PMA/FEC Direct PHY Intel FPGA IP Core Soft CSR Registers

The following table describes the F-Tile PMA/FEC Direct PHY Intel® FPGA IP soft CSR registers. These registers are available for every fracture and their function is the same as the single rate IP. However, to control these registers for different fractures, you need to add an additional 0x4000 offset to the starting address. See Address Offset for the 12 Fractures Available in One F-Tile for the complete list of registers for each fracture.
Table 27.   F-Tile PMA/FEC Direct PHY Intel® FPGA IP Soft CSR Registers
Byte Address Bit Offset Name Description Access Reset Value
16’h800 - 16’h818 N/A Existing single rate F-Tile PMA/FEC Direct PHY Intel® FPGA IP soft CSR registers. Refer to F-Tile PMA/FEC Direct PHY Intel FPGA IP Register Map for more information.
16’h81C
Note: This register is only available in the F-Tile PMA/FEC Direct PHY Multirate Intel® FPGA IP.
[0] fracture_active

1: Indicates that this fracture is active.

0: Indicates that the fracture is not active and not in use.

Read-only Reflects startup profile value.

Byte Address Name Description
1st Fracture
16’h800 - 16’h818 Existing F-Tile PMA/FEC Direct PHY Intel® FPGA IP soft CSR space for 1st fracture Refer to F-Tile PMA/FEC Direct PHY Intel FPGA IP Register Map for more information.
16’h81C 1st fracture_active Status bit that indicates that this fracture is active; 1'b1 indicates that the fracture is active.
16’h820 - 16’h82C Refer to F-Tile PMA/FEC Direct PHY Multirate Intel FPGA IP Core Reconfiguration Soft CSR Registers for the details.
