NOTES:
1. Timing depends on which signal is aserted last,

.
2. Timing depends on which signal is deaserted first,

3. t
BDD
delay is required only in a case where the opposite port is completing
a write operation to the same address location. For simultanious read operations
BUSY
has no relationship to valid output data.
