Description
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. When using an oscillator frequency above 12 MHz, the
reset input function of P1.5 must be enabled. An external circuit is required to
hold the device in reset at power-up until V

applications, an external brownout detect circuit may be required to hold the
device in reset when V
Ground: 0 V reference.
Power supply: This is the power supply voltage for normal operation as well as Idle
mode and Power-down mode.
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.
