Using ISR() Macro in AVR-GCC

[Vivek B]

Hi folks,

My code is handling both timer0 interrupt and SPI interrupt. And I
don't want to loose any of the SPI interrupts and hence thought of
making the timer0 ISR to work in NOBLOCK mode. But when i use

ISR(TIMER0_COMP_vect, ISR_NOBLOCK)
{
/* Code */

}

the compiler gives an error: "macro "ISR" passed 2 arguments, but
takes just 1"

where it works fine for

ISR(TIMER0_COMP_vect)
{
/* Code */

}

-----------------------!!!!!!!!----------------------

Right now I am implementing the code as follows

ISR(TIMER0_COMP_vect)
{
sei();
/* Code */

}

But I would like to use the first one. Isn't the first implementation
suppose to work??

Anyone has any guess why it is not working...

Thank you ..

Vivek.

The gcc library maintainers read the forums at avrfreaks.net. Ask this
question there. You will get an answer in minutes. I think ISR macro
replaces SIG and INTR macros, one of which was re-entrant.
