The generation of FINT determines the beginning
of the result phase. For each of the commands, a
defined set of result bytes has to be read from the
FDC before the result phase is complete. These
bytes of data must be read out for another
command to start.

RQM and DIO must both equal "1" before the
result bytes may be read. After all the result bytes
have been read, the RQM and DIO bits switch to
"1" and "0" respectively, and the CB bit is cleared,
indicating that the FDC is ready to accept the next
command.
