As with all C2000 devices, the muxed GPIO pins default to GPIO inputs (hi-impedance) at reset. This condition is not explicitly stated in text in the documentation, but is immediately obvious by looking at the default state of the GPxMUXy and GPxDIRy registers in the System Control User's Guide.
Note: For GPIO pins which are MUXed with the JTAG functions (for example, on F2802x devices), the TRSTn pin controls whether the pins default to GPIO or JTAG at reset.
Note: Even though all GPIO are set to be high impedance on reset, several have internal pull-ups which are also enabled at reset. See the Pull-up/Pull-down section below.
