Value
RCOMP_EN.
RW 1
Enable Rcomp. When set, the Integrated Memory Controller will do the
programmed blocking of requests and send indications.
RCOMP_CMD_DCLK.
RW 2
Delay from the start of an RCOMP command blocking period in which the
command rcomp update is done. Program this field to 15 for all configurations.
RCOMP_LENGTH.
Number of Dclks during which all commands are blocked for an RCOMP update.
RW 9
Data RCOMP update is done on the last DCLK of this period. Program this field
to 31 for all configurations.
RCOMP_INTERVAL.
RW 0
Duration of interval between Rcomp in increments of tRefI. Register value is
tRefI-1. For example a setting of 0 will produce an interval of tRefI.
