Synopsis
#include
intrinsic void SET_VECTOR(int vectnum,void (*hndlr)(void));
where:
•
vectnum
is the interrupt vector number for which the interrupt handler
hndlr
is to be
set
•
hndlr
is the interrupt handler function pointer. The
hndlr
function must be declared
to be of the interrupt type with parameters and return as
void
(no parameters and no
return)
The compiler supports the following values for
vectnum
for the ZNEO CPU:
Returns
None
Example
#include
extern void interrupt isr_timer0(void);
void main(void)
{
SET_VECTOR(TIMER0, isr_timer0); /* setup TIMER0 vector */
}
TDI
TDI
(test and disable interrupts) is an intrinsic function that supports users creating their
own critical sections of code. It returns the previous interrupt status and disables inter-
rupts. It is intended to be paired with a later call to
RI()
, which will restore the previously
existing interrupt status. See the
section on page 183 for a discussion of that function.
