GPIO Input Data Read Register
The GPIO Input Data Read Register reports the state of the GPIO inputs, as configured in the
GPIO Polarity Register. When a bit is defined as active-high this register will read a "1" when the
input is high, and a "0" when it is low. When a bit is defined as active-low, this register will read a
"1" when the input is low, and a "0" when it is high. This register contains the same contents as
the GPIO Data Register, only it is read only.
