6.16.1.1. Enabling the PRBS Data Generator in Non Bonded designs
You must perform a sequence of read-modify-writes to addresses 0x006, 0x007,
0x008, and 0x110 to enable either the PRBS data generator. 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 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.

6.16.1.1.1. Examples of Enabling the PRBS9 and PRBS31 Pattern Generators in Non
Bonded designs
Example 5. Enabling the PRBS9 pattern generator in 10-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- -
1100
3. Perform a read-modify-write to address x007[7:0] with the following bits: 8’b0010
- - - -
4. Perform a read-modify-write to address x008[7:0] with the following bits: 8’b -
000 - - - -
5. Perform a read-modify-write to address x110[7:0] with the following bits: 8’b - - -
- - 100
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.
