Notes:
The EMR controls the functions beyond those controlled by the mode register. These
additional functions are special features of the mobile device that helps reduce overall
system power consumption. They include temperature-compensated self refresh
(TCSR) control, partial-array self refresh (PASR), and output drive strength.
The EMR is programmed via the MODE REGISTER SET command (BA1 = 1, BA0 = 0) and
retains the stored information until it is programmed again or the device loses power.
1. Each READ command may be to any bank. DQM is LOW.
2. For CL = 2, DQM should be taken LOW at READ command. For CL = 3, DQM should be taken
