The external clock signal must be
300
mVpp connected to XOSC_Q1 using a
DC block (10 nF). Set
XOSC_BYPASS = 0 in the
INTERFACE register when using
an external clock signal with low
amplitude or a crystal.
0 - VDD
The external clock signal must be
V connected to XOSC_Q1. No DC
block shall be used. Set
XOSC_BYPASS = 1 in the
INTERFACE register when using
a full-swing digital external clock.
