The Node Configuration bit indicates the NOD/MODE.

The Hardware/Software Priority Status bit indicates the SW mode.

The ISO/IEC specification defines bit 5.13 as the Remote Fault bit, and bit 19.13 is functionally identical to
bit 5.13. The Remote Fault bit is set based on the Link Control Word received from the remote link partner.
When this bit is a logic:

See
The ICS1893CF includes the Auto-MDI/MDIX crossover feature. The Auto-MDI/MDIX feature automatically
selects the correct MDI or MDIX configuration to match the cable plant by automatically swapping transmit
and receive signal pairs at the PHY. Auto-MDI/MDIX is defaulted on but may be disabled for test purposes
using either the AMDIX_EN (pin 10) or by writing (bits 19. 9:8). See Table 7-22 for AMDIX_EN (19,9) and
MDI_MODE (19,8) operation.
When AMDIX_EN (bit 19,9) is set to 0, the twisted pair transmit/receive is forced by the MDI_MODE bit
(19,8).
Note:
Table 7-22. AMDIX_EN (Pin 10) and Control Bits 19. 9:8
In Node mode:
The ICS1893CF will only operate in the Node Configuration.
The (MDIO) register bits control the ICS1893CF configuration.
The ICS1893CF will only operate in the Software Configuration.
Zero, it indicates the remote link partner does not detect a Link Fault.
One, it indicates to an STA that the remote link partner detects a Link Fault.
– The SQE Test default setting is enabled.
– The Carrier Sense signal (CRS) is asserted in response to either transmit or receive activity.

AMDIX_EN
ICS1893CF Data Sheet Rev. J - Release
Holding (Pin 10) AMDIX_EN low will also disable the Auto_MDIX function and force pins TP_AP
and TP_AN to be the transmit pair and TP_BP and TP_BN to be the receive pair. AMDIX_EN has
a built in 50K Ohm internal pull-up.
