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.
