tn_p24_soft_isr

#define tn_p24_soft_isr	(		_func,
			_psv
	)		_tn_soft_isr_internal(_func, _psv, )

ISR wrapper macro for software context saving.

Usage looks like the following:

tn_p24_soft_isr(_T1Interrupt, auto_psv)
{
   //-- clear interrupt flag
   IFS0bits.T1IF = 0;

   //-- do something useful
}

Which should be used for system interrupts, instead of standard way:

void __attribute__((__interrupt__, auto_psv)) _T1Interrupt(void)

Where _T1Interrupt is the usual PIC24/dsPIC ISR name, and auto_psv (or no_auto_psv) is the usual attribute argument for interrupt.
