11.4 Enabling a Peripheral

In order to enable a peripheral that is clocked by a generic clock, the following parts of the system needs to be configured:

• A running clock source.
• A clock from the generic clock generator must be configured to use one of the running clock sources, and the generator must be enabled.
• The generic clock multiplexer that provides the generic clock signal to the peripheral must be configured to use a running generic clock generator, and the generic clock must be enabled.
• The user interface of the peripheral needs to be unmasked in the PM. If this is not done the peripheral registers will read all ‘0’s and any writing attempts to the peripheral will be discarded.
