Example 6. Enabling the PRBS31 pattern generator in 64-bit mode
1. Perform the necessary steps from steps 1 to 7 in Steps to Perform Dynamic
Reconfiguration.
2. Perform a read-modify-write to address x006[7:0] with the following bits: 8’b01- -
0100
3. Perform a read-modify-write to address x007[7:0] with the following bits: 8’b0000
- - - -
4. Perform a read-modify-write to address x008[7:0] with the following bits: 8’b -
001 - - - -
5. Perform a read-modify-write to address x110[7:0] with the following bits: 8’b - - -
- - 011
6. Perform the necessary steps from steps 9 to 12 in Steps to Perform Dynamic
Reconfiguration.
Note: A dash (-) indicates that the corresponding bit value should not be modified during
read-modify-write.

6.16.1.2. Enabling the PRBS Data Generator in Bonded Designs
You must perform a sequence of read-modify-writes to addresses 0x006, 0x007,
0x008, and 0x110, 0x111and to enable either the PRBS data generator in bonded
designs. To enable either the PRBS data generator, follow these steps:
1. Perform the necessary steps from steps 1 to 7 in Steps to Perform Dynamic
Reconfiguration.
2. Perform a read-modify-write to address 0x006 according to Register Map for PRBS
Generators for bonded and non bonded designs.
3. Perform a read-modify-write to address 0x007 according to Register Map for PRBS
Generators for bonded and non bonded designs.
4. Perform a read-modify-write to address 0x008 according to Register Map for PRBS
Generators for bonded and non bonded designs.
5. Perform a read-modify-write to address 0x110 with the specified width. This data
width is either 64-bit or 10-bit.
6. Perform a read-modify-write to address 0x111 according to Register Map for PRBS
Generators for bonded and non bonded designs. You must read and save the value
in the register 0x111[5:0] before changing the x1_clock_source_sel setting to
xN non bonding.
7. Perform the necessary steps from steps 9 to 12 in Steps to Perform Dynamic
Reconfiguration.
To disable the PRBS generator, write the original values back into the read-modify-
write addresses in Register Map for PRBS Generators for bonded and non bonded
designs.
