1. All banks (banks 0, 1, 2, and 3).
2. Two banks (banks 0 and 1; BA1 = 0).
3. One bank (bank 0; BA1 = BA0 = 0).
4. Half bank (bank 0; BA1 = BA0 = row address MSB = 0).
5. Quarter bank (bank 0; BA1 = BA0; row address MSB = row address MSB -1 = 0).
For further power savings during self refresh, the partial-array self refresh (PASR) feature
allows the controller to select the amount of memory that will be refreshed during self
refresh. The following refresh options are available.
WRITE and READ commands occur to any bank selected during standard operation, but
only the selected banks in PASR will be refreshed during self refresh. It is important to
note that data in banks 2 and 3 will be lost when the two-bank option is used.
Bits E5 and E6 of the EMR can be used to select the driver strength of the DQ outputs.
This value should be set according to the application’s requirements.
