Timing Diagram
Write to Slave
1. Slave signals readiness to receive data from host.
2. Slave drops INRDY.
3. Host drops R/W to indicate a write.
4. Host drops STROBE.
5. Host places data on the bus.
6. Host raises STROBE indicating data is valid.
7. Slave raises INRDY, latching the data.
8. INT3 is triggered when INRDY rises.

Read from Slave
1. Slave signals readiness to send data to host.
2. Slave drops OUTRDY.
3. Host raises R/W to indicate a read.
4. Host drops STROBE.
5. Slave places data on the bus.
6. Host raises STROBE after reading the data.
7. Slave raises OUTRDY.
8. INT4 is triggered when OUTRDY rises.
