CRdy/-Bsy
This bit is set to one (1) when the bit RRdy/-Bsy changes state. This bit can also be
written by the host.
CWProt
This bit is set to one (1) when the RWprot changes state. This bit may also be written by
the host.

This bit is used to determine the internal state of the Rdy/-Bsy signal. This bit may be
used to determine the state of the Ready/-Busy as this pin has been reallocated for use
as Interrupt Request on an I/O card. When written, this bit acts as a mask for writing the
corresponding bit CRdy/-Bsy.
