Extended MCAS latency from READ command. Number of clock cycles between registration of a
READ command by the SDRAM and the availability of the first output data. If a READ command is
registered at clock edge
clock edge
for the total CAS latency. Note that if this bit is set, then 8 clocks are added to the programmed value
in TIMING_CFG_1[CASLAT].

Reserved, should be cleared.
Control Adjust. Controls the amount of delay to add to the lightly loaded control signals w/ respect to
all other DRAM address and command signals. The signals affected by this field are MODT[0:3],
MCS[0:3], and MCKE[0:3]
000 MODT[0:3], MCS[0:3], and MCKE[0:3] are launched aligned with the other DRAM address and
001 MODT[0:3], MCS[0:3], and MCKE[0:3] are launched 1/2 platform cycle later than the other
010 MODT[0:3], MCS[0:3], and MCKE[0:3] are launched 1 platform cycle later than the other
011 MODT[0:3], MCS[0:3], and MCKE[0:3] are launched 3/2 platform cycles later than the other
100 MODT[0:3], MCS[0:3], and MCKE[0:3] are launched 2 platform cycles later than the other
101 MODT[0:3], MCS[0:3], and MCKE[0:3] are launched 5/2 platform cycles later than the other
