Description
Port 0:
Port 0 is an I/O port with a user-configurable output type. During reset Port 0
latches are configured in the input only mode with the internal pull-up disabled. The
operation of Port 0 pins as inputs and outputs depends upon the port configuration
selected. Each port pin is configured independently. Refer to
Section 8.12.1 “Port
configurations”
and
Table 13 “DC electrical characteristics”
for details.
The Keypad Interrupt feature operates with Port 0 pins.
All pins have Schmitt triggered inputs.
Port 0 also provides various special functions as described below:
P0.2 —
Port 0 bit 2.
CIN2A —
Comparator 2 positive input.
KBI2 —
Keyboard input 2.
P0.4 —
Port 0 bit 4.
CIN1A —
Comparator 1 positive input.
KBI4 —
Keyboard input 4.
P0.5 —
Port 0 bit 5.
CMPREF —
Comparator reference (negative) input.
KBI5 —
Keyboard input 5.
Port 1:
Port 1 is an I/O port with a user-configurable output type. During reset Port 1
latches are configured in the input only mode with the internal pull-up disabled. 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
Section 8.12.1 “Port configurations”
and
Table 13 “DC
electrical characteristics”
for details. P1.5 is input only.
All pins have Schmitt triggered inputs.
Port 1 also provides various special functions as described below:
P1.0 —
Port 1 bit 0.
TxD —
Serial port transmitter data.
P1.1 —
Port 1 bit 1.
RxD —
Serial port receiver data.
P1.5 —
Port 1 bit 5 (input only).
RST —
External Reset input during Power-on or if selected via UCFG1. When
functioning as a reset input 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. Also used during a power-on sequence to force In-System
Programming mode.
Ground:
0 V reference.
Power Supply:
This is the power supply voltage for normal operation as well as Idle
and Power-down modes.
