To establish the SDRAM’s mode of operation it must, after power-up, be initialized by means of programming. The
programming is undertaken by issuing a Mode Register Set command that passes data along the SDRAM address
lines to the Mode Register. The UPM fully supports the noted command by means of a dedicated Memory Address
Register as well as the UPM command run option. Mode Register programming values are shown in
"SDRAM Mode Register
In order to operate the SDRAM at speeds higher than 66Mhz read the application note at
