Hi everybody,

 

I've read the examples about the TIMER.

 

Can you explain difference between definition of interrupt?

 

example 1:

     sysreg_bit_set(sysreg_MODE2, TIMEN);    // Global Timer Enable. Enables (if set, = 1) or disables (if cleared,
                                           
     sysreg_bit_set(sysreg_IMASK, TMZHI);   //Timer Expired High Priority. Unmasks the TMZHI interrupt
                                            //(if set, = 1), or masks the TMZHI interrupt (if cleared, = 0). A TMZHI
                                            //occurs when the timer decrements to zero. or masks the DPII interrupt (if cleared, = 0).

     interrupts (SIG_TMZ, Timer_isr);    // enable high priority timer interrupt

 

 

 

example 2:

     interrupt(SIG_TMZ,Timer_isr);

 

Thank you,

Milos
