Signal Tables
21.1
Table 21-6 on page 1251 lists the signals based on number of possible pin assignments. This table
can be used to plan how to configure the pins for a particular functionality. Application Note AN01274
Configuring Tiva™ C Series Microcontrollers with Pin Multiplexing provides an overview of the pin
muxing implementation, an explanation of how a system designer defines a pin configuration, and
examples of the pin configuration process.
Note: All digital inputs are Schmitt triggered.

Buffer Type^a Description
TTL
GPIO port D bit 0.
Analog
OD
Analog-to-digital converter input 15.
I²C module 3 clock. Note that this signal has an active pull-up. The
corresponding port pin should not be configured as open drain.
TTL
SSI module 1 clock.
TTL
SSI module 3 clock.
TTL
32/64-Bit Wide Timer 2 Capture/Compare/PWM 0.
TTL
GPIO port D bit 1.
Analog
OD
Analog-to-digital converter input 14.
I²C module 3 data.
TTL
SSI module 1 frame signal.
TTL
SSI module 3 frame signal.
TTL
32/64-Bit Wide Timer 2 Capture/Compare/PWM 1.
TTL
GPIO port D bit 2.
Analog Analog-to-digital converter input 13.
TTL
SSI module 1 receive.
TTL
SSI module 3 receive.
TTL
Optionally used in Host mode to control an external power source
to supply power to the USB bus.
TTL
32/64-Bit Wide Timer 3 Capture/Compare/PWM 0.
TTL
GPIO port D bit 3.
Analog Analog-to-digital converter input 12.
TTL
SSI module 1 transmit.
TTL
SSI module 3 transmit.
TTL
Optionally used in Host mode by an external power source to
indicate an error state by that power source.
TTL
32/64-Bit Wide Timer 3 Capture/Compare/PWM 1.
Power Positive supply for I/O and some logic.
Power Ground reference for logic and I/O pins.
Power
The positive supply for the analog circuits (ADC, Analog
Comparators, etc.). These are separated from VDD to minimize
the electrical noise contained on VDD from affecting the analog
functions. VDDA pins must be supplied with a voltage that meets
the specification in Table 22-5 on page 1257, regardless of system
implementation.
