You can obtain this value if you do not delay configuration by extending the nCONFIG or nSTATUS low pulse width.
You can obtain this value if you do not delay configuration by externally holding the nSTATUSlow.
If nSTATUSis monitored, follow the tST2CK specification. If nSTATUSis not monitored, follow the tCF2CK specification.
N is the DCLK-to-DATAratio and fDCLK is the DCLKfrequency the system is operating.
e minimum and maximum numbers apply only if you use the internal oscillator as the clock source for initializing the device.
