AT91SAM7S32 Preliminary
The AT91SAM7S32 embeds a wide range of peripherals. Table 4 defines the Peripheral
Identifiers of the AT91SAM7S32. A peripheral identifier is required for the control of the
peripheral interrupt with the Advanced Interrupt Controller and for the control of the
peripheral clock with the Power Management Controller.
