7.8 Register 6: Auto-Negotiation Expansion Register
7.8.1 IEEE Reserved Bits (bits 6.15:5)
ICS1893Y-10 Rev F 1/20/04
Table 7-13
Auto-Negotiation process.
Note:
Table 7-13. Auto-Negotiation Expansion Register (register 6 [0x06])
† As per the IEEE Std 802.3u, during any write operation to any bit in this register, the STA must write the default value
The ISO/IEC specification reserves these bits for future use. When an STA:

ICS uses some reserved bits to invoke auxiliary functions. To ensure proper operation of the ICS1893Y-10,
an STA must maintain the default value of these bits. Therefore, ICS recommends that an STA always write
the default value of any reserved bits during all management register write operations.
Reserved bits 5.15:5 are Command Override Write (CW) bits. When the Command Register Override bit
(bit 16.15) is logic:

Reads a reserved bit, the ICS1893Y-10 returns a logic zero.
Writes to a reserved bit, the STA must use the default value specified in this data sheet.
