Parallel falling edge detection testable input
To connect the crystal/ceramic oscillator to the
main system clock generator. When inputting the
external clock, input the external clock to pin X1,
and the reverse phase of the external clock to pin
X2.
To connect the crystal oscillator to the subsystem
clock generator.
When the external clock is used, pin XT1 inputs
the external clock. In this case, pin XT2 must be
left open.
