software has forced the value driven on CKE, that value will continue to be forced until software clears the
CKE_CNTL bits. At that time, the DDR controller will continue to drive the CKE signals to the same value
forced by software until another event causes the CKE signals to change (i.e., self refresh entry/exit, power
down entry/exit).

of the DDR controller during a mode register set command, is significant only when this register is used to
issue a mode register set command or a precharge or precharge all command.
For a mode register set command, this field contains the data to be written to the selected mode register.
For a precharge command, only bit five is significant:
0 Issue a precharge command; MD_SEL selects the logical bank to be precharged
1 Issue a precharge all command; all logical banks are precharged
