PORT1 consists of the two 8-bit bidirectional I/O ports P1L

and P1H. 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. PORT1 is used as the

16-bit address bus (A) in demultiplexed bus modes and also

after switching from a demultiplexed bus mode to a

multiplexed bus mode.

The following PORT1 pins also serve for alternate functions:

XTAL2 137 O

XTAL1 138 I

XTAL2: Output of the oscillator amplifier circuit.

XTAL1: Input to the oscillator amplifier and input to

the internal clock generator

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.
