PORT0 consists of the two 8-bit bidirectional I/O ports P0L
and P0H. Each pin can be programmed for input (output
driver in high-impedance state) or output.
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
16-bit
P0L.0 – P0L.7:
D0 – D7
D0 - D7
P0H.0 – P0H.7: I/O
D8 - D15
Multiplexed bus modes:
Data Path Width: 8-bit
16-bit
P0L.0 – P0L.7: AD0 – AD7 AD0 - AD7
P0H.0 – P0H.7: A8 - A15 AD8 - AD15
Note: At the end of an external reset (EA = ’0’) PORT0 also
may input configuration values.

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 (also after
switching from a demultiplexed to a multiplexed bus mode).
The following PORT1 pins also serve for alt. functions:
CC60
CAPCOM6: Input / Output of Channel 0
COUT60 CAPCOM6: Output of Channel 0
CC61
CAPCOM6: Input / Output of Channel 1
COUT61 CAPCOM6: Output of Channel 1
CC62
CAPCOM6: Input / Output of Channel 2
COUT62 CAPCOM6: Output of Channel 2
COUT63 Output of 10-bit Compare Channel
CTRAP CAPCOM6: Trap Input
CTRAP is an input pin with an internal pullup resistor. A low
level on this pin switches the CAPCOM6 compare outputs to
the logic level defined by software (if enabled).
CC22IO CAPCOM2: CC22 Capture Inp./Compare Outp.
