3.0 Registers
3.10 Performance Monitoring Registers
LCV[7:0]
If LATCH_CNT [addr 046] is inactive, reading LCV [addr 055] clears the entire LCV[15:0] count value.
LCV[15:8]
FEBE[7:0]
If LATCH_CNT [addr 046] is inactive, reading FEBE [addr 056, 057] clears the entire FEBE[9:0] count value.
FEBE[9:8]
Reading BERR transfers the most recent 12-bit count from the internal PRBS error counter to BERR[11:0],
then clears the internal error counter without affecting the reported BERR[11:0] value. Subsequent reads of
BERR MSB [addr 059] report the BERR [11:8] count value latched when BERR LSB was last read.
