Precharge Command
This command is used to precharge or close a bank that has been activated. Precharge is initiated by issuing a Precharge command at
the rising edge of the clock. The Precharge command can be used to precharge each bank respectively or all banks simultaneously.
The Bank addresses BA0 and BA1 select the bank to be precharged. After a Precharge command, the analog delay tRP has to be met
until a new Activate command can be initiated to the same bank.
