9. Peripherals
9.1 Peripheral Identifiers
Table 9-1 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.
