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 12 “Static 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:
P0.1 —
Port 0 bit 1.
KBI1 —
Keyboard input 1.
AD10 —
ADC1 channel 0 analog input.
P0.2 —
Port 0 bit 2.
KBI2 —
Keyboard input 2.
AD11 —
ADC1 channel 1 analog input.
P0.3 —
Port 0 bit 3.
CIN1B —
Comparator 1 positive input.
AD12 —
ADC1 channel 2 analog input.
P0.4 —
Port 0 bit 4.
CIN1A —
Comparator 1 positive input.
AD13 —
ADC1 channel 3 analog input.
DAC1 —
Digital to analog converter output.
P0.5 —
Port 0 bit 5.
CMPREF —
Comparator reference (negative) input.
CLKIN —
External clock input.
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 12 “Static
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.
