CFG_PRBS_CNT_Mode

R/W

0x0

1b = Continuous mode, when one of the PRBS counters reaches max value, pulse is generated and counter starts counting from zero again

0b = Single mode, When one of the PRBS counters reaches max value, PRBS checker stops counting.

2CFG_PRBS_CHK_EnableR/W0x1Enable PRBS checker xbar (to receive data). Must be enabled for packet counters to work
1CFG_PKT_GEN_PRBSR/W0x0

If bit[1] is set:

(a) When pkt_gen_en is set, PRBS packets are generated continuously

(b) When pkt_gen_en is cleared, PRBS RX checker is still enabled

If bit [1] is cleared:

(a) When pkt_gen_en is set, non - PRBS packet is generated

(b) When pkt_gen_en is cleared, PRBS RX checker is disabled as well

0PKT_GEN_EnableR/W0x0

1b = Enable packet/PRBS generator

0b = Disable packet/PRBS generator
