DDR2 Control Register 4 (DDR2CTL4)
The
register includes the programmable parameters associated

with the DDR2 extended mode register 2 (
DDR2 control register bit definition. All the values are defined in terms of
number of clock cycles. Values written into this register are loaded into
the DDR2 extended mode register 3 during power up (or when the force

before starting the initialization sequence.
This register's contents should not be changed while DDR2 inter-
face is active. Also whenever this register contents are changed an
initialization sequence must be executed to reflect this register con-
tents in to the DDR2 extended mode register 3.
