3.3.10 Functional ports
The functional port pins are listed in Table 5. Note that most port pins have options to independently configure slew rate control and after reset this will be set
to the slowest option. In addition different Pad Types have different slew rate performance and this may mean that the default slew rate needs to be changed to
match the performance required for each signal. Refer to column “Pad Type” when selecting and configuring port pins to determine if slew rate adjustment may
be required.
