11. Peripherals

11.1

Peripheral Identifiers

Table 11-1 defines the Peripheral Identifiers of the SAM3U. A peripheral identifier is required for

the control of the peripheral interrupt with the Nested Vectored Interrupt Controller and for the

control of the peripheral clock with the Power Management Controller.

Note that some Peripherals are always clocked. Please refer to the table below.
