Set Burst

The Set Burst command specifies the number of bytes

to be output during a Read Burst command before the

device wraps around. It supports both SPI and SQI pro-

tocols. To set the burst length the host drives CE# low,

sends the Set Burst command cycle (C0H) and one

data cycle, then drives CE# high. After power-up or

reset, the burst length is set to eight Bytes (00H). See

Table 5-2 for burst length data and Figures 5-11 and 5-

12 for the sequences.
