Burst Enable Specification
Enables or disables 8-burst access for a 16-bit bus
width or 16-burst access for an 8-bit bus width during
16-byte access. If this bit is set to 0, 2-burst access is
performed four times when the bus width is 16 bits and
4-burst access is performed four times when the bus
width is 8 bits. To use a device that does not support
8-burst access or 16-burst access, set this bit to 1.
0: Enables 8-burst access for a 16-bit bus width and
16-burst access for an 8-bit bus width.
1: Disables 8-burst access for a 16-bit bus width and
16-burst access for an 8-bit bus width.
