device that supports Big Endian systems, make sure to that the bytes of the CPU and DiskOnChip
2000 match.
Note: Processors, such as the PowerPC, also change the bit ordering within the bytes. Failing to

The TrueFFS driver supports 8-bit, 16-bit, and 32-bit bus architectures. Support for the 16-bit and
32-bit bus architectures, typically used in RISC processors, can be achieved by using the LSB of the
data bus as follows:

For 16-bit address boundary shifts, shift the address lines by one , so that the host address line
A1 connects to DiskOnChip 2000 address line A0, the host address line A2 connects to
DiskOnChip 2000 line A1, and so on.
For 32-bit address boundary shifts, shift the address lines by two , so that the host address line
A2 connects to DiskOnChip 2000 address line A0, the host address line A3 connects to
DiskOnChip 2000 line A1, and so on.
follow these rules results in improper connection of DiskOnChip 2000, and prevents the
TrueFFS driver from identifying DiskOnChip 2000.
