Clock Source Select
Switch to external clock at start-up only. If there is no
clock signal on the IFC pin when the chip is switched to
the external clock source, the chip does not allow the
switch (CLK_SEL remains zero, operation continued). If
the external clock disappears with CLK_SEL already set,
the chip will reset (PLL out of lock) and run on with the
internal clock.
