AT91SAM9R64/RL64
10.2 Peripheral Identifiers
The Table 10-1 defines the Peripheral Identifiers of the AT91SAM9R64/RL64. A peripheral iden-
tifier 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.
Note: Setting AIC, SYSIRQ, LCDC and IRQ bits in the clock set/clear registers of the PMC has no effect.
