not affect the push-pull Port I/O. Furthermore, the weak pullup is turned off on an open-drain output that is driving
a 0 to avoid unnecessary power dissipation.
The third and final step is to initialize the individual resources selected using the appropriate setup registers.
Initialization procedures for the various digital resources may be found in the detailed explanation of each available
function. The reset state of each register is shown in the figures that describe each individual register.
