Note that when the host is sending data to the
FIFO of the FDC, the internal sector count will be
complete when the FDC reads the last byte
37
from its side of the FIFO. There may be a delay in
the removal of the transfer request signal of up to
the time taken for the FDC to read the last 16
bytes from the FIFO. The host must tolerate this
delay.
Result Phase
The generation of the interrupt 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.
