For applications using X1/X2 for OSCCLK, the user must characterize their specific oscillator start-up time as it is dependent on circuit/layout external to the device. See Table 5-21
for more information. For applications using INTOSC1 or INTOSC2 for OSCCLK, see Section 188.8.131.52
. Oscillator start-up time does not apply to applications using a single-ended crystal on the X1 pin, as it is powered externally to the device.
