Similar to the Read Command, a Write Command with auto-precharge can not be interrupted by a command
to the same bank. It can be interrupted by a Read or Write Command to the other bank, however. The auto-
precharge function is unaffected by the interrupting command and will begin as normally scheduled according
to burst length.
