SET_VECTOR
SET_VECTOR is a Zilog intrinsic function provided by the compiler to specify the address
of an interrupt handler for an interrupt vector. Because the interrupt vectors of the Z8
Encore! microcontroller are usually in ROM, they cannot be modified at run time. The
SET_VECTOR function works by switching to a special segment and placing the address of
the interrupt handler in the vector table. No executable code is generated for this state-
ment. Calls to the
SET_VECTOR intrinsic function must be placed within a function body.
Synopsis
#include

intrinsic void SET_VECTOR(int vectnum,void (*hndlr)(void));
In the above example:
•
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 type interrupt with no parameters and return void (no parameters and no
return).

The following values for vectnum are supported for most Z8 Encore! parts (all those that
do not fall into the more specific categories covered in the next two tables):
