Read with auto precharge to Read command interval
1. Different bank: When some banks are in the active state, the second read command (another bank) is executed. Even
when the first read with auto-precharge is a burst read that is not yet finished, the data read by the second command is
valid. The internal auto-precharge of one bank starts at the next clock of the second command.
2. Same bank: The consecutive read command (the same bank) is illegal.
Write with auto precharge to Write command interval
1. Different bank: When some banks are in the active state, the second write command (another bank) is executed. In the
case of burst writes, the second write command has priority. The internal auto-precharge of one bank starts 2 clocks later
from the second command.
