Data Sheet
Function
PORT0 consists of the two 8-bit bidirectional I/O ports P0L
and P0H. 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.
In case of an external bus configuration, PORT0 serves as
the address (A) and address/data (AD) bus in multiplexed
bus modes and as the data (D) bus in demultiplexed bus
modes.
Demultiplexed bus modes:
Data Path Width:
8-bit
P0L.0 – P0L.7:
D0 – D7
P0H.0 – P0H.7:

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
CAPCOM2: CC24 Capture Input
CC25IO
CAPCOM2: CC25 Capture Input
CC26IO
CAPCOM2: CC26 Capture Input
CC27IO
CAPCOM2: CC27 Capture Input
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.
