Read Command

Description

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.

Burst Read

Reads a block of locations from the data array or mask array as a

burst.

The internal register (RBURADR) specifies the starting address and

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.
