3.1.2 External Clock
An external clock may be applied to the OSCIN in-
put with the OSCOUT pin not connected, as
shown on
Figure 4
. The t
OXOV
specifications does
not apply when using an external clock input. The
equivalent specification of the external clock
source should be used instead of t
OXOV
(see ).
