Data Output Configuration
Set Read Configuration Register
The Set Read Configuration Register (RCR) command sets the burst order, frequency
configuration, burst length, and other parameters.
A two-bus cycle command sequence initiates this operation. The Read Configuration
Register data is placed on the lower 16 bits of the address bus (A[15:0]) during both
bus cycles. The Set Read Configuration Register command is written along with the
configuration data (on the address bus). This is followed by a second write that
confirms the operation and again presents the Read Configuration Register data on the
address bus. The Read Configuration Register data is latched on the rising edge of
ADV#, CE#, or WE# (whichever occurs first). This command functions independently of
the applied V
mode. The Read Configuration Register’s contents can be examined by writing the Read
Identifier command and then reading location 05h. See
