Notes:
1. To achieve maximum clock performance, the read clock edge will need to be set for rising edge operation in the configuration
register (RCE=1).
2. Test points are 10% and 90% points for rise/fall times. All others timings are measured at 50% point.
3. With 30 pF (16 MHz) load SO to GND.
4. See Preliminary Designation page 31
