void deregisterISR

(

ISRpointer

isr

)

Deregister an interrupt service routine.

Deregister an interrupt service routine. Every time an interrupt occures every registered ISR will be executed. The number of ISRs is limited to 5 by default.

Parameters:

isr	Function pointer to the iterrupt service routine that needs to be deregistered.

void initInterrupt

(

void

)

Initialize interrupt functionality.

This routine initializes interrupt functionality for Dwengo board. Sets some global variables.

void registerISR

(

ISRpointer

isr

)
