Connect the return side to the signal ground level.  Make sure the signals satisfy electrical characteristics.  Set the leading edge and trailing edge times to 0.5ms or less.  Do not ignore Ack or BUSY signals during a data transfer. Ignoring such signals may result in data corruption.  Make the interface cables as short as possible. 114

CAUTION
A signal name with a rule above it indicates an “L” active signal.
Bidirectional communications cannot take place, unless all signal names for both sides
correspond to each other.
Connect all signal lines using a twisted-pair cable. Connect the return side to the signal
ground level.
Make sure the signals satisfy electrical characteristics.
Set the leading edge and trailing edge times to 0.5ms or less.
Do not ignore Ack
or BUSY signals during a data transfer. Ignoring such signals may
result in data corruption.
Make the interface cables as short as possible.
