Read 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.
However, DQM must be set High so that the output buffer becomes High-Z before data input. The internal auto-
precharge of one bank starts at the next clock of the second command.

2. Same bank: The consecutive write command from read with auto precharge (the same bank) is illegal. It is
necessary to separate the two commands with a bank active command.
Write 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.
However, in case of a burst write, data will continue to be written until one clock before the read command is
executed. The internal auto-precharge of one bank starts at 2 clocks later from the second command.
