9.2.4 Port Output Modification Register
The port output modification register contains control bits that make it possible to
individually set, reset, or toggle the logic state of a single port line by manipulating the
output register.
Note: Register Pn_OMR is virtual and does not contain any flip-flop. A read action
delivers the value of zero. One 8 or 16-bits write behaves as a 32-bit write padded
with zeros.
