Input to the oscillator amplifier and input to the internal clock generator.
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 (P3.14 is missing) 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.
Some Port 3 pins also serve for alternate functions:
