If a GPIO is tri-stated (GPn_ENA = 0), then the read value of the corresponding GPn_LVL field is
invalid.
Table 81 GPIO Level Register
The power domain for each GPIO is controlled using the GPn_PWR_DOM registers as described in
Table 82. The power domain for GPIO13 - GPIO16 is fixed; these pins are referenced to TPVDD.

GPIOn level.
When GPn_FN = 0h and GPn_DIR
= 0, write to this bit to set a GPIO
output.
Read from this bit to read GPIO
input level.
When GPn_POL is 0, the register
contains the opposite logic level to
the external pin.
