Peripheral Interrupts and Clock Control
System Interrupt
External Interrupts
Table 9-1.
The System Interrupt in Source 1 is the wired-OR of the interrupt signals coming from:
The clock of these peripherals cannot be deactivated and Peripheral ID 1 can only be used
within the Advanced Interrupt Controller.
All external interrupt signals, i.e., the Fast Interrupt signal FIQ or the Interrupt signals IRQ0 to
IRQ2, use a dedicated Peripheral ID. However, there is no clock control associated with these
peripheral IDs.
The AT91SAM9260 features 3 PIO controllers (PIOA, PIOB, PIOC) that multiplex the I/O lines of
the peripheral set.
Each PIO Controller controls up to 32 lines. Each line can be assigned to one of two peripheral
functions, A or B.
