to TRUE. Two ISERDES modules are in a master-slave configuration for a data width of

Guidelines for Using the Bitslip Submodule
Set the BITSLIP_ENABLE attribute to TRUE. When BITSLIP_ENABLE is set to FALSE, the
Bitslip pin has no effect. In a master-slave configuration, the BITSLIP_ENABLE attribute in
both modules must be set to TRUE.
To invoke a Bitslip operation, the BITSLIP port must be asserted High for one CLKDIV
cycle. In SDR mode, Bitslip cannot be asserted for two consecutive CLKDIV cycles; Bitslip
must be deasserted for at least one CLKDIV cycle between two Bitslip assertions. In both
SDR and DDR mode, the total latency from when the ISERDES captures the asserted
Bitslip input to when the “bit-slipped” ISERDES outputs Q1–Q6 are sampled into the
FPGA logic by CLKDIV is two CLKDIV cycles.
