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:
8-bit data bus: P0H = I/O, P0L = D7 - D0
16-bit data bus: P0H = D15 - D8, P0L = D7 - D0
Multiplexed bus modes:
8-bit data bus: P0H = A15 - A8, P0L = AD7 - AD0
16-bit data bus: P0H = AD15 - AD8, P0L = AD7 - AD0
Note: At the end of an external reset (EA = 0) PORT0 also
may input configuration values
PORT1
IO
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:
P1L.0 79 I/O CC60
CAPCOM6: Input / Output of Channel 0
P1L.1 80 O
COUT60 CAPCOM6: Output of Channel 0
P1L.2 81 I/O CC61
CAPCOM6: Input / Output of Channel 1
P1L.3 82 O
COUT61 CAPCOM6: Output of Channel 1
P1L.4 83 I/O CC62
CAPCOM6: Input / Output of Channel 2
P1L.5 84 O
COUT62 CAPCOM6: Output of Channel 2
P1L.6 85 O
COUT63 Output of 10-bit Compare Channel
P1L.7 86 I
CTRAP CAPCOM6: Trap Input
CTRAP is an input pin with an internal pull-up resistor. A low
level on this pin switches the CAPCOM6 compare outputs to
the logic level defined by software (if enabled).
I/O CC22IO CAPCOM2: CC22 Capture Inp./Compare Outp.
