Timing Waveform of Write with
BUSY
(M/

= V
IL
)
NOTES:
1. t
WH
must be met for both
BUSY
input (SLAVE) and output (MASTER).
2.
BUSY
is asserted on port "B" blocking R/
W
"B"
, until
BUSY
"B"
goes HIGH.

NOTES:
1. To ensure that the earlier of the two ports wins. t

for the reading port.
4. If M/

= V
IL
(SLAVE), then
BUSY
is an input (
BUSY
"A"
= V
IH
and
BUSY
"B"
= "don't care", for this example).
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".
