    Hi,

    HEL is the signal for a specified slave device by simply decoding the HADDR of the bus master.

    The specified slave can start response by catching "(HEL==1) & (HTRANS==NONSEQ)".

    The relationship with HWRITE, HWDATA or HRDATA depends on the HREADY(OUT) which is issuing by the slave. These will be the same times as the first HREADY(OUT).

    Best regards,

    Yasuhiko Koumoto.
