8.13 Register 18: 10Base-T Operations Register
8.13.1 ICS Reserved (bit 18.15)
ICS1892, Rev. D, 2/26/01
The 10Base-T Operations Register provides an STA with the ability to monitor and control the ICS1892
activity while the ICS1892 is operating in 10Base-T mode.
Note:

ICS reserves this bit for future use. Functionally, this bit is equivalent to an IEEE Reserved bit. When this

In general, ICS uses some reserved bits to invoke auxiliary functions. To ensure proper operation of the
ICS1892, 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.
