This bit controls the software reset function. Setting this bit to logic one initiates an ICS1893 software reset
during which all Management Registers are set to their default values and all internal state machines are
set to their idle state. For a detailed description of the software reset process, see
“ Software Reset”
During reset, the ICS1893 leaves bit 0.15 set to logic one and isolates all STA management register
accesses. However, the reset process is not complete until bit 0.15 (a Self-Clearing bit), is set to logic zero,
which indicates the reset process is terminated.

The Control Register is accessible through the MII Management Interface.
Its operation is independent of the MAC/Repeater Interface configuration.
It is fully compliant with the ISO/IEC Control Register definition.
