output pin. If GPIO[n] is programmed as an input, then software can read the bit to determine the
level on the corresponding input pin. These bits correspond to GPIO that are in the resume well,

0 = The corresponding GPIO will function normally.
1 = If the corresponding GPIO is programmed as an output, the output signal will blink at a
rate of approximately once per second. The high and low times have approximately 0.5
seconds each. The GP_LVL bit is not altered when this bit is set.
