Description
Bank Active Mode
Specifies to access whether in auto-precharge mode
(using READA and WRITA commands) or in bank active
mode (using READ and WRIT commands).
0: Auto-precharge mode (using READA and WRITA
1: Bank active mode (using READ and WRIT commands)
Note: Bank active mode can be used only in area 3. In this
Reserved
These bits are always read as 0. The write value should
always be 0.
Number of Bits of Row Address for Area 3
Specify the number of bits of the row address for area 3.
00: 11 bits
01: 12 bits
10: 13 bits
11: Reserved (setting prohibited)
Reserved
This bit is always read as 0. The write value should always
be 0.
Number of Bits of Column Address for Area 3
Specify the number of bits of the column address for area
3.
00: 8 bits
