8-bit microcontroller with 10-bit A/D converter
P1.3/INT0/SDA

I/O
P1.3 — Port 1 bit 3 (open-drain when used as output).
I
INT0 — External interrupt 0 input.
I/O
SDA — I2C serial data input/output.
P1.4/INT1

I
P1.4 — Port 1 bit 4.
I
INT1 — External interrupt 1 input.
P1.5/RST

I
P1.5 — Port 1 bit 5 (input only).
I
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.
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 VDD has reached its
specied level. When system power is removed VDD will fall below
the minimum specied operating voltage. When using an oscillator
frequency above 12 MHz, in some applications, an external
brownout detect circuit may be required to hold the device in reset
when VDD falls below the minimum specied operating range.
P1.6/OCB

I/O
P1.6 — Port 1 bit 6.

I/O
P1.7 — Port 1 bit 7.
O
OCC — Output Compare C.
I
AD04 — ADC0 channel 4 analog input.
P2.0 to P2.7
I/O
Port 2: Port 2 is an 8-bit I/O port with a user-congurable output type.
During reset Port 2 latches are congured in the input only mode with the
internal pull-up disabled. The operation of Port 2 pins as inputs and
outputs depends upon the port conguration selected. Each port pin is
congured independently. Refer to Section 7.13.1 “Port congurations”
All pins have Schmitt triggered inputs.
Port 2 also provides various special functions as described below:
P2.0/ICB/AD07
1
25
I/O
P2.0 — Port 2 bit 0.
I
ICB — Input Capture B.
I
AD07 — ADC0 channel 7 analog input.
P2.1/OCD/
AD06

26
I/O
P2.1 — Port 2 bit 1.
O
OCD — Output Compare D.
I
AD06 — ADC0 channel 6 analog input.
P2.2/MOSI
13
9
I/O
P2.2 — Port 2 bit 2.
I/O
MOSI — SPI master out slave in. When congured as master, this pin is
output; when congured as slave, this pin is input.
P2.3/MISO
14
10
I/O
P2.3 — Port 2 bit 3.
I/O
MISO — When congured as master, this pin is input, when congured
as slave, this pin is output.
