11. Peripheral Identifiers
The AT91SAM7A3 embeds a wide range of peripherals. Table 11-1 defines the Peripheral Iden-
tifiers of the AT91SAM7A3. Unique peripheral identifiers are defined for both the AIC and the
PMC.
Note:
1. Setting SYSC and ADC bits in the clock set/clear registers of the PMC has no effect. The Sys-
tem Controller and ADC are continuously clocked.
