The normal operating mode is selected by setting M7 and M8 to zero; the other combi-
nations of values for M7 and M8 are reserved for future use. The programmed burst
length applies to both read and write bursts.
Reserved states must not be used; unknown operation or incompatibility with future
versions may result.
When M9 = 0, the burst length programmed via M0–M2 applies to both READ and
WRITE bursts; when M9 = 1, the programmed burst length applies to READ bursts, but
write accesses are single-location accesses.
The extended mode register controls the functions beyond those controlled by the mode
register. These additional functions are special features of the mobile device. They
include temperature-compensated self refresh (TCSR) control, partial-array self refresh
(PASR), and output drive strength.
The extended mode register is programmed via the MODE REGISTER SET command
with BA = 1 and BA = 0 and retains the stored information until it is programmed again
or the device loses power.
The extended mode register must be loaded when all banks are idle and no bursts are in
progress, and the controller must wait
Violating any of these requirements will result in unspecified operation.
