Table 4.3 lists the interrupt number, request pending flag location in the Interrupt Request
Registers 0 to 3 (IRRn, n=0 - 3), and interrupt level field (ILRn, n=0 - 31) in the Interrupt
Level Control Registers 0 to 15 (ILCONn, n=0 - 15) for each source. The final column gives a
fixed priority for use in selecting from among interrupt requests with the same interrupt level.
The first column uses the following symbols:
nEFIQ: Interrupt request from external fast interrupt request pin
nEIR[n] (n=0 - 7): Interrupt request from nEIR[n] pin
EVENTn (n=0 - 5): Capture event or compare match interrupt request from Flexible Timer
FTMOVn (n=0 - 5): Timer overflow interrupt request from Flexible Timer (FTM) channel n
WDINT: Watchdog Timer (WDT) interrupt request signal from Time Base Generator (TBG)
RVINT: Receive ready interrupt request from Asynchronous Serial Interface (ASI)
TRINT: Transmit ready interrupt request from Asynchronous Serial Interface (ASI)
BGINT: Baud rate interrupt request from Asynchronous Serial Interface (ASI)
CSINTn (n=0,1): Transfer complete interrupt request from Clock Synchronous Serial Interface
ADINT: A/D conversion complete interrupt request from Analog-to-Digital Converter (ADC)
Internal Interrupt Requests
Internal interrupt requests come from the following on-chip peripherals:
If the interrupt level specified for the corresponding source is higher than the highest level
flagged in the Current Interrupt Level Register (CILR), which holds interrupt level flags for the
interrupts currently being processed, the interrupt controller sends the CPU an IRQ exception
request. The CPU only accepts this exception request if the I bit in its Current Program Status
Register (CPSR) is "0."
