1. All values apply to Octal and Quad-SPI mode.

2. Guaranteed by characterization results.

3. DHQC must be set to reach the mentioned frequency.

4. Using PC2 or PC3 I/O in the data bus decreases the frequency to 47 MHz.

5. Delay block bypassed.

6. Using PC2 or PC3 I/O in the data bus adds 4 ns to this timing value.
