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 the next clock of the second
command.

2. Same bank:
The consecutive read command from write with auto precharge (the same bank) is illegal. It
is necessary to separate the two commands with a bank active command.
