Pullup/Pulldown Inhibit Registers (PDINHIBR1/2/3) to enable internal pull-up/down resistors.
GPIOs conigured as outputs
Cannot apply software configurations until bootloader completes and application code runs. During boot, I/O current could be higher than after configuring for low power.
Some pins do not support software termination and must be terminated externally - these pins do not have "IPU" or "IPD" under the OTHER column in Terminal Functions table in the data sheet. For more information, see C5000 DSP Based Low-Power System Design.
