Notes:
11. Minimum times occur with maximum oscillator frequency. Maximum times occur with minimum oscillator
frequency.
12. Write latency is the sum of the delay through the master serializer and slave deserializer, plus the flight time
across the flex cable and I/O propagation delays.
13. Assumes propagation delay across the flex cable and through the I/Os of 20ns.
14. Total read latency t_PD-RD is the sum of the Read-Control Phase latency (t_PD-RDC) and the Read-Data Phase latency
(t_PD-RDD). t_PD-RD = t_PD-RDC+ t_PD-RDD.
15. Read-Control latency is the sum of the delay through the master serializer and slave deserializer, plus flex cable
flight times and I/O propagation delays.
16. Read Data latency is the sum of the delay through the slave serializer and master deserializer, plus flex cable
flight times and I/O propagation delays.
17. SPI–Write latency is the sum of the delay through the master serializer and slave deserializer, plus the flight time
across the flex cable and I/O propagation delays.
