NOTES:
1. To ensure that the earlier of the two ports wins. t
APS
is ignored for M/

4. If M/

= V
IL
(slave),
BUSY
is an input. Then for this example
BUSY
"A"
= V
IH
and
BUSY
"B"
input is shown above.
5. All timing is the same for left and right ports. Port "A" may be either the left or right port. Port "B" is the port opposite from port "A".

2.
BUSY
is asserted on port "B" blocking R/

BUSY
"B" goes High.
3. All timing is the same for left and right ports. Port "A" may be either the left or right port. Port "B" is the port opposite from port "A".
