Full Page Burst

Full page burst length is available for only the sequential burst type. Full page burst read / write is

repeated untill a Precharge or a Burst Terminate command is issued. In case of the full page burst,

a read / write with auto-precharge command is illegal.

Single Write

When sigle write mode is set, burst length for write is always one, independently of Burst Length

defined by (A2-0).
