Byte Test (BYTE_TEST)
This field reflects the current byte ordering
Byte Order Test Register (BYTE_TEST)
This read-only register can be used to determine the byte ordering of the current configuration. Byte
ordering is a function of the host data bus width and endianess. Refer to
on page 99
Note: This register can be read while the LAN9312 is in the reset or not ready states.
The BYTE_TEST register can optionally be used as a dummy read register when assuring minimum
write-to-read or read-to-read timing. Refer to
