Port 0: Port 0 is an 4-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.
Port 1: Port 1 is an 6-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 ei-
ther 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 de-
pends upon the port configuration selected. Each of the configurable port pins are pro-
grammed 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.
Port 2: Port 2 is a 2-bit I/O port with a user-configurable output type. Port 2 latches are con-
figured 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 Electri-
cal Characteristics for details.
Port 2 also provides various special functions as described below.
Ground: 0 V reference.
Power Supply: This is the power supply voltage for normal operation as well as Idle and
Power Down modes.

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.
Output from the oscillator amplifier (when a crystal oscillator
option is selected via the EPROM configuration).
