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
Generators for bonded and non bonded
3. Perform a read-modify-write to address 0x007 according to
Generators for bonded and non bonded
4. Perform a read-modify-write to address 0x008 according to
Generators for bonded and non bonded
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
designs.
