NOTES:
1. All timing is the same for left and right ports. Port 'A' may be either left or right port. Port 'B' is the opposite from port 'A'.
2. If tAPS 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).
