is value is applicable if you do not delay configuration by extending the nCONFIGor nSTATUSlow pulse width.
is value is applicable 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.
e minimum and maximum numbers apply only if you choose the internal oscillator as the clock source for initializing the device.
