The FDC supports terminal count explicitly

If the last sector to be transferred is a partial

implicit functions and TC is that they return
"abnormal termination" result status.
status indications can be ignored if they were

Note that when the host is sending data to the
FIFO of the FDC, the internal sector count will

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
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.
