Related Information
75 You can obtain this value if you do not delay configuration by extending the nCONFIG or nSTATUS low pulse width.
76 If nSTATUS is monitored, follow the tST2CK specification. If nSTATUS is not monitored, follow the tCF2CK specification.
77 N is the DCLK-to-DATA ratio and fDCLK is the DCLK frequency the system is operating.
78 The minimum and maximum numbers apply only if you use the internal oscillator as the clock source for initializing the device.
