When change SRRU from non-zero value to zero value or vice versa, It will need to wait about 300 nanoseconds delay before
the slew rate control to be real function as setting. When enter STOP, to save the power, the slew rate control will be force to off
state. After wakeup from STOP, it will also need to wait about 300 nanoseconds before slew rate control to be function as setting.

Port U pull device select—Determine pull device polarity on input pins
This register serves a dual purpose by selecting the polarity of the active interrupt edge as well as selecting a pull-up
or pull-down device if enabled.
1 A pull-down device is connected to the associated Port U pin, if enabled by the associated bit in register PERU and
0 A pull-up device is connected to the associated Port U pin, if enabled by the associated bit in register PERU and
Port U Slew Rate Register—Determine the slew rate on the pins
1 Enable the slew rate control and disables the digital input buffer
