8.4.1.3
The chip select configuration (CSn_CONFIG_2) registers shown in
refresh address decode in each chip select.
If chip select interleaving is enabled, then all fields in the lower interleaved chip select are used, and the
other registers’ fields are unused.

Reserved
Partial array self refresh config. Controls the bits that are placed on MA[2:0] during the write to
the EMRS(2) register when the automatic hardware DRAM initialization is used
(DDR_SDRAM_CFG[BI] is cleared when DDR_SDRAM_CFG[MEM_EN] is set). If this field is
a non-zero value, then it overrides the least significant 3 bits in
DDR_SDRAM_MODE_2[ESDMODE2] during the automatic initialization for chip select n . In
addition, if a non-zero value is programmed in this field, then the address decode for chip select
n is optimized for partial array self refresh, as shown in
Multiplexing.
