2.4.13
This register controls the UTOPIA loopbacks on the PHY side of the IMA block.
2.4.14
This register provides a single bit that can be used by a diagnostic test routine to verify the connectivity of the
microprocessor address lines to the IMA device. This bit is read-only.
2.4.15
This register provides an isolated 8 bit storage register that can be used by a diagnostic test routine to verify the
connectivity of the microprocessor data lines to the IMA device.
