12. Read-Control latency is the sum of the delay through the master serializer and slave deserializer, plus flex cable
13. Read Data latency is the sum of the delay through the slave serializer and master deserializer, plus flex cable
14. SPI-Write latency is the sum of the delay through the master serializer and slave deserializer, plus the flight time
15. Timing allows the device to completely reset prior to powering down.
16. Internal reset filter allows assertion prior to completion of read or write date transfer.
17. Timing ensures that last write transaction is complete prior to going into standby.
