PRELIMINARY DATASHEET
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.
6.5.4
Result Phase
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.
