Although a Read Command with auto-precharge cannot be interrupted by a command to the same bank, it
can be interrupted by a Read or Write Command to a different bank. If the interrupting command is issued
before auto-precharge begins then the precharge function will begin with the new command. The bank being
auto-precharged may be reactivated after the delay tRP.
