11.9.3 Endian and byte lane to each access
The external bus interface corresponds to both little endian and big endian. These switches are
set with external pin, BIGEND. External data bus width is set with external pin,
MPX_MODE_1[1:0].
Correlation of each endian, external data bus width, and byte lane to each access is shown
below.
