Crystal Connection
If the internal oscillator is used for clock
generation (clock modes 0b, 6, 7) the external
crystal has to be connected to these pins. The
internal oscillator should be powered up
(GMODE:OSCPD = ’0’) and the signal shaper
may be activated (GMODE:DSHP = ’0’).
Moreover, XTAL1 may be used as input for a
common clock source to both SCCs, provided by
an external clock generator (oscillator). In this
case the oscillator unit may be powered down and
it is recommended to bypass the shaper of the
internal oscillator unit by setting bit ’DSHP’ to ’1’.
