6. Enabling Peripheral Clocks
the associated interrupt to PCKRDYx has been enabled in the PMC_IER register. All param-
eters in PMC_PCKx can be programmed in a single write operation.
If the CSS and PRES parameters are to be modified, the corresponding Programmable
clock must be disabled first. The parameters can then be modified. Once this has been
done, the user must re-enable the Programmable clock and wait for the PCKRDYx bit to be
set.
Once all of the previous steps have been completed, the peripheral clocks can be enabled
and/or disabled via registers PMC_PCER0, PMC_PCER, PMC_PCDR0 and PMC_PCDR.
