† As per the IEEE Std 802.3u, during any write operation to any bit in this register, the STA must write the default value  
to all Reserved bits.  
8.8.1 IEEE Reserved Bits (bits 6.15:5)  
The ISO/IEC specification reserves these bits for future use. When an STA:  
Reads a reserved bit, the ICS1893AF returns a logic zero.  
Writes to a reserved bit, the STA must use the default value specified in this data sheet.  
ICS uses some reserved bits to invoke auxiliary functions. To ensure proper operation of the ICS1893AF,  
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:  
Zero, the ICS1893AF isolates all STA writes to CW bits.  
One, an STA can modify the value of these bits
