If A10 is high when a Write Command is issued, the Write with Auto-Precharge function is initiated. The bank undergoing auto-
precharge cannot be reactivated until tDAL, Data-in to Active delay, is satisfied.
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 a different bank, however. The interrupting command will terminate the
write. The bank undergoing auto-precharge can not be reactivated until tDAL is satisfied.
