Read Command
Description
0
Single Read
Reads a single location of the data array, mask array, external SRAM,
or device registers. All access information is applied on the DQ Bus.
Reads a block of locations from the data array or mask array as a
burst.
The internal register (RBURADR) specifies the starting address and
1
Burst Read
the length of the data transfer from the data array or mask array, and it
auto-increments the address for each access.
All other access information is applied on the DQ Bus.
Note: The device registers and external SRAM can only be read in
single-read mode.
