Implementation
The Interrupt Service Routine (ISR)
Blinking an LED is implemented inside an
ISR
triggered by the ERU which generates
interrupt requests
according to its configuration.
The method implementing the ISR needs to be assigned a
priority
and a
CPU core
responsible for its execution. This is done with the macro
IFX_INTERRUPT(isr,
vectabNum, priority)
.
When triggered, the ISR
blinks
the LED by
toggling
the
state
of the connected pin
using the function
IfxPort_setPinState()
.
