I/O
Port 0: Port 0 is an 8-bit I/O port with a user-configurable output type. Port 0 latches are configured in
the quasi-bidirectional mode and have either ones or zeros written to them during reset, as determined
by the PRHI bit in the UCFG1 configuration byte. The operation of port 0 pins as inputs and outputs
depends upon the port configuration selected. Each port pin is configured independently. Refer to the
section on I/O port configuration and the DC Electrical Characteristics for details.
The Keyboard Interrupt feature operates with port 0 pins.
Port 0 also provides various special functions as described below.

I/O
Port 1: Port 1 is an 8-bit I/O port with a user-configurable output type, except for three pins as noted
below. Port 1 latches are configured in the quasi-bidirectional mode and have either ones or zeros
written to them during reset, as determined by the PRHI bit in the UCFG1 configuration byte. The
operation of the configurable port 1 pins as inputs and outputs depends upon the port configuration
selected. Each of the configurable port pins are programmed independently. Refer to the section on I/O
port configuration and the DC Electrical Characteristics for details.
Port 1 also provides various special functions as described below.

Timer/counter 0 external count input or overflow output.
SCL
I2C serial clock input/output. When configured as an output, P1.2 is open

P1.3
INT0
External interrupt 0 input.
SDA
I2C serial data input/output. When configured as an output, P1.3 is open

P1.4
INT1
External interrupt 1 input.

P1.5
RST
External Reset input (if selected via EPROM configuration). A low on this pin
resets the microcontroller, causing I/O ports and peripherals to take on their
default states, and the processor begins execution at address 0. When used
as a port pin, P1.5 is a Schmitt trigger input only.

Port 2: Port 2 is a 2-bit I/O port with a user-configurable output type. Port 2 latches are configured in the
quasi-bidirectional mode and have either ones or zeros written to them during reset, as determined by
the PRHI bit in the UCFG1 configuration byte. The operation of port 2 pins as inputs and outputs
depends upon the port configuration selected. Each port pin is configured independently. Refer to the
section on I/O port configuration and the DC Electrical Characteristics for details.
