XTAL1:
Input to the oscillator amplifier and input
to the internal clock generator
XTAL2:
Output of the oscillator amplifier circuit.
To clock the device from an external source, drive
XTAL1, while leaving XTAL2 unconnected.
Minimum and maximum high/low and rise/fall times
specified in the AC Characteristics must be
observed.

Port 3 is a 15-bit bidirectional I/O port. It is bit-wise
programmable for input or output via direction bits.
For a pin configured as input, the output driver is put
into high-impedance state. Port 3 outputs can be
configured as push/pull or open drain drivers. The
Port 3 pins serve for following alternate functions:
T6OUT
GPT2 Timer T6 Toggle Latch Output
CAPIN
GPT2 Register CAPREL Capture Input
T3OUT
GPT1 Timer T3 Toggle Latch Output
T3EUD
