P1.2–P1.7
I
Port 1.2 to Port 1.7 have no digital output driver; they can function as a digital
9–12
11–14
input for which ‘0’ must be written to the port bit. As a digital input, these pins
must be driven high or low externally.
These pins also have the following analog functionality:
P1.2/DAC/IEXC1 I/O
The voltage output from the DAC or one or both current sources (200 A or
2
200 A) can be configured to appear at this pin.
P1.3/AIN5/IEXC2 I/O
Auxiliary ADC Input or one or both current sources can be configured at this pin.
P1.4/AIN1
I
Primary ADC, Positive Analog Input
P1.5/AIN2
I
Primary ADC, Negative Analog Input
P1.6/AIN3
I
Auxiliary ADC Input or Muxed Primary ADC, Positive Analog Input
P1.7/AIN4/DAC
I/O
Auxiliary ADC Input or Muxed Primary ADC, Negative Analog Input. The voltage
output from the DAC can also be configured to appear at this pin.

MISO
I/O
Master Input/Slave Output for the SPI Interface. There is a weak pull-up on this
input pin.
15
17
RESET
I
Reset Input. A high level on this pin for 16 core clock cycles while the oscillator is
running resets the device. There is an internal weak pull-down and a Schmitt
trigger input stage on this pin.
16–19,
18–21,
P3.0–P3.7
I/O
Bidirectional port pins with internal pull-up resistors. Port 3 pins that have 1s written
22–25
24–27
to them are pulled high by the internal pull-up resistors, and in that state can be used
as inputs. As inputs, Port 3 pins being pulled externally low will source current
because of the internal pull-up resistors. When driving a 0-to-1 output transition,
a strong pull-up is active for two core clock periods of the instruction cycle.
Port 3 pins also have various secondary functions including:
P3.0/RXD
I/O
Receiver Data for UART Serial Port
P3.1/TXD
I/O
Transmitter Data for UART Serial Port
P3.2/
INT0
I/O
External Interrupt 0. This pin can also be used as a gate control input to Timer 0.
P3.3/
INT1
I/O
External Interrupt 1. This pin can also be used as a gate control input to Timer 1.
P3.4/T0/
I/O
Timer/Counter 0 External Input. If the PWM is enabled, an external clock may be
PWMCLK
input at this pin.
P3.5/T1
I/O
Timer/Counter 1 External Input
P3.6/
WR
I/O
External Data Memory Write Strobe. Latches the data byte from Port 0 into an
external data memory.
P3.7/
RD
I/O
External Data Memory Read Strobe. Enables the data from an external data
memory to Port 0.

SCLOCK
I/O
Serial Interface Clock for Either the I
2C or SPI Interface. As an input, this pin is a
Schmitt-triggered input and a weak internal pull-up is present on this pin unless
it is outputting logic low. This pin can also be directly controlled in software as a
digital output pin.
27
MOSI/SDATA
I/O
Serial Data I/O for the I
2C Interface or Master Output/Slave Input for the SPI
Interface. A weak internal pull-up is present on this pin unless it is outputting logic
low. This pin can also be directly controlled in software as a digital output pin.
