Note that MD_EN, SET_REF, and SET_PRE are mutually exclusive; only
one of these fields can be set at a time.
Mode enable. Setting this bit specifies that valid data in MD_VALUE is ready to be written to DRAM as one
of the following commands:
The specific command to be executed is selected by setting MD_SEL. In addition, the chip select must be
chosen by setting CS_SEL.MD_EN is set by software and cleared by hardware once the command has
been issued.
0 Indicates that no mode register set command needs to be issued.
1 Indicates that valid data contained in the register is ready to be issued as a mode register set command.
Reserved
Select chip select. Specifies the chip select that will be driven active due to any command forced by
software in DDR_SDRAM_MD_CNTL.

0 Indicates that no refresh command needs to be issued.
1 Indicates that a refresh command is ready to be issued.
DDR_SDRAM_MD_CNTL[CS_SEL]. This bit will be set by software and cleared by hardware once the
command has been issued.
0 Indicates that no precharge all command needs to be issued.
1 Indicates that a precharge all command is ready to be issued.
