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.
3. All timng is the same for left and right ports. Port"A" may be either left or right port. Port "B" is the opposite fromport "A".
NOTES:
1. To ensure that the earlier of the two ports wins. t
APS
is ignored for Slave (IDT70125).

NOTES:
1. All timng is the same for left and right ports. Port “A” may be either left or right port. Port “B” is the opposite fromport “A”.
2. If t

is not satisified, the
BUSY
will be asserted on one side or the other, but there is no guarantee on which side
BUSY
will be asserted
(70121 only).
