Reserved states should not be used as unknown operation or incompatibility with future
versions may result.
COMMAND
COMMAND
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 and/or test modes. The
programmed burst length applies to both read and write bursts.
Test modes and reserved states should not be used because 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 (nonburst) accesses.
