Function
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:
CC24IO
CC25IO
CC26IO
CC27IO
XTAL2:
XTAL1:
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.
XTAL3:
XTAL4:
To clock the device from an external source, drive XTAL3,
while leaving XTAL4 unconnected. Minimum and maximum
high/low and rise/fall times specified in the AC
Characteristics must be observed.
