12. About Burst Type Control
At MRS A

BL=1, 2, 4, 8 and full page.At Full page wrap-around.
At MRS A
3
= "1". See the BURST SEQUENCE TABLE. (BL=4,8)
BL=4, 8. At BL=1, 2 Interleave Counting = Sequential Counting
Every cycle Read/Write Command with random column address can realize
Random Column Access.
That is similar to Extended Data Out (EDO) Operation of conventional DRAM.

13. About Burst Length Control

At MRS A

At auto precharge, t
RAS
should not be violated.
Before the end of burst, Row precharge command of the same bank stops read/write
burst with Row precharge.

RDL
= 1 with DQM, valid DQ after burst stop is 1, 2 for CAS latency 2, 3 respectively.
During read/write burst with auto precharge, RAS interrupt can not be issued.

Using burst stop command, any burst length control is possible.
Before the end of burst, new read/write stops read/write burst and starts new
read/write burst.
During read/write burst with auto precharge, CAS interrupt can not be issued.
