Single-chip 16-bit/32-bit microcontrollers
6.5 Interrupt controller
The VIC accepts all of the interrupt request inputs and categorizes them as FIQ, vectored
IRQ, and non-vectored IRQ as dened by programmable settings. The programmable
assignment scheme means that priorities of interrupts from the various peripherals can be
dynamically assigned and adjusted.
FIQ has the highest priority. If more than one request is assigned to FIQ, the VIC
combines the requests to produce the FIQ signal to the ARM processor. The fastest
possible FIQ latency is achieved when only one request is classied as FIQ, because then
the FIQ service routine does not need to branch into the interrupt service routine but can
run from the interrupt vector location. If more than one request is assigned to the FIQ
class, the FIQ service routine will read a word from the VIC that identies which FIQ
source(s) is (are) requesting an interrupt.
Vectored IRQs have the middle priority. Sixteen of the interrupt requests can be assigned
to this category. Any of the interrupt requests can be assigned to any of the 16 vectored
IRQ slots, among which slot 0 has the highest priority and slot 15 has the lowest.
Non-vectored IRQs have the lowest priority.
The VIC combines the requests from all the vectored and non-vectored IRQs to produce
the IRQ signal to the ARM processor. The IRQ service routine can start by reading a
register from the VIC and jumping there. If any of the vectored IRQs are pending, the VIC
provides the address of the highest-priority requesting IRQs service routine, otherwise it
provides the address of a default routine that is shared by all the non-vectored IRQs. The
default routine can read another VIC register to see what IRQs are active.
6.5.1 Interrupt sources
Each peripheral device has one interrupt line connected to the Vectored Interrupt
Controller, but may have several internal interrupt ags. Individual interrupt ags may also
represent more than one interrupt source.
6.6 Pin connect block
The pin connect block allows selected pins of the microcontroller to have more than one
function. Conguration registers control the multiplexers to allow connection between the
pin and the on chip peripherals. Peripherals should be connected to the appropriate pins
prior to being activated, and prior to any related interrupt(s) being enabled. Activity of any
enabled peripheral function that is not mapped to a related pin should be considered
undened.
The pin control module with its pin select registers denes the functionality of the
microcontroller in a given hardware environment.
After reset all pins of Port 0 are congured as input with the following exceptions: If the
DBGSEL pin is HIGH (Debug mode enabled), the JTAG pins will assume their JTAG
functionality for use with EmbeddedICE and cannot be congured via the pin connect
block.
