Output pad loading and slew rate
The output pins on the MCF5441x devices have programmable slew rates. Table 12 lists the rise/fall time for pins based on the
type of pad used for the signal, the value programmed into the appropriate field of the slew rate control registers, and capacitive
loading. Refer to Table 5 for a list of the external signals to pad connections.
NOTE
To allow the I/O interfaces to run at their maximum frequency, set their respective slew rate
select values to 11.
