// Array of Callback function

);

Description

[(*func())[9]]

Return value

True if all parameters are valid and exclusive; otherwise false.

R_INTC_CreateExtInterrupt

Remarks • Please see the notes on callback function use

• A callback function is executed by the interrupt processing function. This means that no other interrupt

can be processed until the callback function has completed.

Program example

#include "r_pdl_intc.h"

/* Declaration of callback function */

Void callbackfunc1 (void);

Void callbackfunc2 (void);

Void callbackfunc3 (void);

Void callbackfunc4 (void);

Void callbackfunc5 (void);

Void callbackfunc6 (void);

Void callbackfunc7 (void);

Void callbackfunc8 (void);

Void callbackfunc9 (void);

void (*CallBackFunc( void ))[9] = { callbackfunc1,

callbackfunc2,callbackfunc3,callbackfunc4,

callbackfunc5,callbackfunc6,callbackfunc7,

callbackfunc8,callbackfunc9

};

void func( void )

{

/* Add a function to manage floating point errors */

R_INTC_CreateExceptionHandlers(CallBackFunc);

}
