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
configurations”
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.
P0.7 — Port 0 bit 7.
T1 — Timer/counter 1 external count input or overflow/PWM output.
CLKOUT — Clock output.
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
characteristics”
All pins have Schmitt triggered inputs.
Port 1 also provides various special functions as described below:
P1.2 — Port 1 bit 2.
T0 — Timer/counter 0 external count input or overflow/PWM output.
