For Port C, unused bits (7-3) are not accessible.
The DR register has a specific behavior according to the selected input/output configuration.
Writing the DR register is always taken into account even if the pin is configured as an input.
Reading the DR register returns either the DR register latch content (pin configured as
output) or the digital value applied to the I/O pin (pin configured as input).
When using open-drain I/Os in output configuration, the value read in DR is the digital value
applied to the I/Opin.
