4. Wrap Boundary Toggle Operation

4. Wrap Boundary Toggle Operation

The Wrap Boundary Toggle Operation allows the device to switch between the linear burst mode

(CA[9:0]) and the 32-byte wrap mode (CA[4:0]). The default setting is Linear Burst.

A Linear Burst allows the device to cross page boundaries . Page boundary crossing is invisible to

the memory controller and limited to the max CLK frequency of 84 MHz. Table 4-1 shows an ex-

ample of the byte sequence in both modes.
