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, DQMU/DQML 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.
Read with Auto Precharge to Write Command Interval (Different bank)
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.
