Peripheral Identifiers

Table 11-1 defines the Peripheral Identifiers of the SAM3X/A series. 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.
