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:

D8 - D15

Multiplexed bus modes:

Data Path Width:

P0H.0 – P0H.7:

A8 - A15

AD8 - AD15

Note: At the end of an external reset (EA = 0) PORT0 also

may input configuration values

I/O

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

and P1H. Each pin can be programmed for input (output

driver in high-impedance state) or output.

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.
