PRBSM |
R/W |
0x0 |
PRBS Single/Continuous Mode.
0x0 = Single mode selected. When BIST Error Counter reaches its max value, the PRBS checker stops counting.
0x1 = Continuous mode selected. When the PRBS counters reach maximum count value, the counter starts counting from zero again.

0x0 |
Generated PRBS Packets.
0x0 = When packet generator is enabled, generate a single packet with constant data. PRBS generation and check is disabled.
0x1 = When packet generator is enabled, generate continuous packets with PRBS data. When packet generator is disabled, PRBS checker is still enabled.
