minimum values of these parameters are:
NOTE:
In each case there will be a small additional delay due to internal propagation delays.
FROM EXTERNAL TO INTERNAL CLOCK
This is accomplished by a low to high transition on the
triggered, to allow for the possibility of a clock signal not being present at OSCIN. Note therefore, that if
a constant high-level signal is applied to OSCIN it will not be possible to switch over to the internal
reference. (Level triggering was not employed for the switch from internal to external reference as this
approach is slower and the internal clock may be running at a much higher frequency than the maximum
allowed external clock rate). When
held low until a falling edge occurs on INTCLK, then the next rising edge of INTCLK will be routed
through to OUT0.
