sor but the same basic rules apply; the row time is still
always 671 clock cycles. Figure 25 provides a slave
mode row timing example for windowing from column
100 to column 200. The row processing is initiated by
raising ROW_STRT and requires 671 clock cycles to
complete. The user can readout the desired window of
columns by lowering LD_SHFT_N and the specified
columns will appear on the output with a 3.5 SYSCLK

delay. Even though the windowed columns can be
readout at the beginning of a row, the user must still
wait the required 671 clock cycles for the row process-
ing to complete before initiating the processing of the
next row with ROW_STRT. Figure 26 provides a slave
mode frame timing example for windowing from row
300 to row 400 which—similar to the master mode—
shows how changing the number of rows in a window
will increase the frame rate.
