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, 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.

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.
