Examples of Enabling the PRBS9 and PRBS31 Pattern Generators
Example 6-4: Enable the PRBS9 pattern generator in 10-bit mode
1. Write 0x02 to address 0x000 of the channel.
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. Write 0x03 to address 0x000 of the channel
Note:
A dash (-) indicates that the corresponding bit value should not be modified
during read-modify-write.
Example 6-5: Enable the PRBS31 pattern generator in 64-bit mode
1. Write 0x02 to address 0x000 of the channel.
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’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. Write 0x03 to address 0x000 of the channel
Note:
A dash (-) indicates that the corresponding bit value should not be modified
during read-modify-write.
Enabling the PRBS Data Checker
You must perform a sequence of read-modify-writes to the Transceiver Native PHY reconfiguration
interface to enable the PRBS checker. You must perform read-modify-writes to addresses 0x00A, 0x00B,
0x00C, and 0x13F. To enable the PRBS checker, follow these steps:
1. Write 0x02 to address 0x000 of the channel.
2. Perform a read-modify-write to address 0x00A with a value of 1'b1 to bit[7].
3. Perform a read-modify-write to address 0x00B according to Table 6-34.
4. Perform a read-modify-write to address 0x00C according to Table 6-34.
5. Perform a read-modify-write to address 0x13F according to Table 6-34.
6. Write 0x03 to address 0x000 of the channel.
To disable the PRBS verifier write the original values back into the read-modify-write addresses listed
above.
