The extended mode register (EMR) controls additional functions beyond those control-
led by the mode register. These additional functions include TCSR, PASR, and output
drive strength.
The EMR is programmed via the LMR command (BA1 = 1, BA0 = 0) and retains the stor-
ed information until it is programmed again or the device loses power.
The EMR must be programmed with E[n:7] set to 0. It must be loaded when all banks
are idle and no bursts are in progress, and the controller must wait the specified time
before initiating any subsequent operation. Violating either of these requirements re-
sults in unspecified operation. After the values are entered, the EMR settings are re-
tained even after exiting deep power-down mode.
This device includes a temperature sensor that is implemented for automatic control of
the self refresh oscillator. Programming the temperature-compensated self refresh
