This command starts the refresh operation. There are two types of refresh operation, the one is auto-refresh, and
the other is self-refresh. For details, refer to the CKE truth table section.
Mode register set [MRS]
The SDRAM has a mode register that defines how it operates. The mode register is specified by the address pins
(A0 to BA0 and BA1) at the mode register set cycle. For details, refer to the Mode Register Configuration. After
power on, the contents of the mode register are undefined, execute the mode register set command to set up the
mode register.
