Important: The value of a reserved bit must be maintained in software. When you modify registers containing reserved bit fields, you must use a read-modify-write operation to preserve state and prevent indeterminate system behavior.

Name:CS to Chip Mapping
Description:Chip select mapping scheme.
Mapping separated into 4 sections: [CS3][CS2][CS1][CS0]
Each section consists of 4 bits to indicate which CS_n signal should be active when command goes to current CS.
Eg: if we set to 16’b0000_0000_0010_0001, CS_n signal will be active on CS0 and CS1 when command occurs on CS0 and CS1 respectively.
Default value should be 16’b1000_0100_0010_0001, only change it for RDIMM single rank design where each RDIMM have 2 CS_n signal but only one is used for actual memory access, one more CS_n bit for RDIMM control word access.
