Read Cycle (Full Page) Interruption Using
the Burst Stop Command
The IS42S16100E/IC42S16100E can output data
continuously from the burst start address (a) to location
a+255 during a read cycle in which the burst length is set
to full page. The IS42S16100E/IC42S16100E repeats the
operation starting at the 256th cycle with the data output
returning to location (a) and continuing with a+1, a+2, a+3,
etc. A burst stop command must be executed to terminate
this cycle. A precharge command must be executed within
the ACT to PRE command period (t
burst stop command.
