[Read with Auto-Precharge Interrupted by Read to another Bank]
Burst write with auto-precharge can be interrupted by write or read to another bank. Next ACT command
can be issued after (BL+tRP) from the READA. Auto-precharge interruption by a command to the same
bank is inhibited.
[Full Page Burst]
Full page burst length is available for only the sequential burst type. Full page burst read or write is
repeated untill a Precharge or a Burst Terminate command is issued. In case of the full page burst, a read
or write with auto-precharge command is illegal.
[Single Write]
When single write mode is set, burst length for write is always one, independently of Burst Length defined
by (A2-0).
