  91 You can obtain this value if you do not delay configuration by extending the nCONFIG or nSTATUS low pulse width. 
 
 
 
  92 You can obtain this value if you do not delay configuration by externally holding nSTATUS low. 
 
 
 
  93 If nSTATUS is monitored, follow the tST2CK specification. If nSTATUS is not monitored, follow the tCF2CK specification. 
 
 
 
  94 The minimum and maximum numbers apply only if you chose the internal oscillator as the clock source for initializing the device.
