Notes to Table 2–43:
(1) You can obtain this value if you do not delay configuration by extending the nCONFIGor nSTATUSlow pulse width.
(2) You can obtain this value if you do not delay configuration by externally holding nSTATUSlow.
(3) The minimum and maximum numbers apply only if you chose the internal oscillator as the clock source for initializing the device.
