Description
INT
I
Falling Edge Trigger
or Falling/Rising Edge
Trigger
External interrupt Schmitt trigger input without pull-high resistor. Choice
falling edge trigger or falling/rising edge trigger by mask option. Falling
edge triggered active on a high to low transition. Rising edge triggered
active on a low to high transition.
OSC1
OSC2
RC or Crystal
OSC1 and OSC2 are connected to an RC network or a crystal (by mask
option) for the internal system clock. In the case of RC operation, OSC2
is the output terminal for 1/4 system clock.
The system clock may come from the crystal, the two pins cannot be
floating.
