3.8 Order of Initialization

For the Interrupt initialization the order of the steps has to be done like in the following

example code.

/* THIS SAMPLE CODE IS PROVIDED AS IS AND IS SUBJECT TO ALTERATIONS. FUJITSU */

/* MICROELECTRONICS ACCEPTS NO RESPONSIBILITY OR LIABILITY FOR ANY ERRORS OR */

/* ELIGIBILITY FOR ANY PURPOSES.

/*---------------------------------------------------------------------------*/

void

InitIrqLevels(void)

{

. . .

ICR08 = 24;

. . .

}

. . .

void

main(void)

{

InitIrqLevels();

__set_il(31);

__EI();

. . .

}

Note that in this example only the initialization flow is shown. Neither the vector definition nor

the Interrupt service routines are shown here.
