To clock the device from an external source, drive XTAL1,
while leaving XTAL2 unconnected. Minimum and maximum

Characteristics (see
Port 3 is a 12-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 following Port 3 pins also serve for alternate functions:
CAPIN

Port 4 is a 6-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 4 can be used to output the segment address lines:
