P1.3 — Port 1 bit 3 (open-drain when used as output).
INT0 — External interrupt 0 input.
SDA — I
P1.4 — Port 1 bit 4.
INT1 — External interrupt 1 input.
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.
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
specified level. When system power is removed V
the minimum specified 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 V
P1.6 — Port 1 bit 6.
OCB — Output Compare B.
P1.7 — Port 1 bit 7.
OCC — Output Compare C.
AD04 — ADC0 channel 4 analog input.
Port 2: Port 2 is an 8-bit I/O port with a user-configurable output type.
During reset Port 2 latches are configured 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 configuration selected. Each port pin is
configured independently. Refer to
and
All pins have Schmitt triggered inputs.
Port 2 also provides various special functions as described below:
P2.0 — Port 2 bit 0.
ICB — Input Capture B.
AD07 — ADC0 channel 7 analog input.
P2.1 — Port 2 bit 1.
OCD — Output Compare D.
AD06 — ADC0 channel 6 analog input.
P2.2 — Port 2 bit 2.
MOSI — SPI master out slave in. When configured as master, this pin is
output; when configured as slave, this pin is input.
P2.3 — Port 2 bit 3.
MISO — When configured as master, this pin is input, when configured
as slave, this pin is output.
