Set Burst (C0h)
The Set Burst command specifies the number of bytes to be output during a Read Bust command
before the device wraps around. To set the burst length the host driver CS# low, sends the Set Burst
command cycle (C0h) and one data cycle, then drivers CS# high, After power-up or reset, the burst
length is set to 8 bytes (00h), please refer to Table 5 for burst length data and Figure 19 for the
sequence. In QPI mode, a cycle is two nibbles, or two clocks, long, most significant nibble first.
The instruction sequence is shown in Figure 19.1 while using the Enable Quad Peripheral Interface
mode (EQPI) (38h) command.
