Always write zeroes to this field.
Data to program into memory mode register 1 for chip select 1.
Holds the memory mode register 1 data for chip select X written during memory initialization. Consult the
memory specification for the fields of this mode register.
The use of this parameter varies based on the memory type connected to this EMI:
For DDR1 memories: This parameter correlates to the extended memory mode register (EMR).
For DDR2 memories: This parameter correlates to the extended memory mode register 1 (EMR1). The EMI
does not support additive latency and therefore the A5:A3 bits should be cleared to 'b000.
For LPDDR1 memories: This parameter has no meaning for this memory type.
This data will be programmed into the appropriate memory register of the DRAM at initialization or when
the write_modereg parameter is set to 'b1.
