Ground: 0 V reference.
Power Supply: This is the power supply voltage for normal, idle, and power down operation.
Port 0: Port 0 is an 8-bit I/O port with a user-configurable output type. Port 0 latches have 1s
written to them and are configured in the quasi-bidirectional mode during reset. 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.
When the external program/data bus is used, Port 0 becomes the multiplexed low data/instruction
byte and address lines 4 through 11.
Port 1: Port 1 is an 8-bit I/O port with a user-configurable output type. Port 1 latches have 1s
written to them and are configured in the quasi-bidirectional mode during reset. The operation of
port 1 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.
Port 1 also provides special functions as described below.
Port 2: Port 2 is an 8-bit I/O port with a user-configurable output type. Port 2 latches have 1s
written to them and are configured in the quasi-bidirectional mode during reset. 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.
When the external program/data bus is used in 16-bit mode, Port 2 becomes the multiplexed high
data/instruction byte and address lines 12 through 19. When the external program/data bus is used in
8-bit mode, the number of address lines that appear on port 2 is user programmable.
Port 3: Port 3 is an 8-bit I/O port with a user configurable output type. Port 3 latches have 1s
written to them and are configured in the quasi-bidirectional mode during reset. the operation of
port 3 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.
Port 3 also provides various special functions as described below.
Reset: A low on this pin resets the microcontroller, causing I/O ports and peripherals to take on
their default states, and the processor to begin execution at the address contained in the reset
vector. Refer to the section on Reset for details.
Address Latch Enable/Program Pulse: A high output on the ALE pin signals external circuitry to
latch the address portion of the multiplexed address/data bus. A pulse on ALE occurs only when it
is needed in order to process a bus cycle.

Address bit 0 of the external address bus when the external data bus is
configured for an 8 bit width. When the external data bus is configured for a 16
bit width, this pin becomes the high byte write strobe.

External interrupt 0 input.
External interrupt 1 input.
Timer 0 external input, or timer 0 overflow output.
Timer 1 external input, or timer 1 overflow output. The value on this pin is
latched as the external reset input is released and defines the default
external data bus width (BUSW). 0 = 8-bit bus and 1 = 16-bit bus.
External data memory low byte write strobe.
External data memory read strobe.
