Interrupt Vectors
Table C-5 presents a suggested interrupt vector map. Most of these
interrupt vectors can be altered under program control. The addresses are
given here in hex, relative to the start of the interrupt vector page, as
determined by the contents of the I-register. These are the default interrupt
vectors set by the boot code in the Dynamic C EPROM.
To “vector” an interrupt to a user function in Dynamic C, use a directive
such as the following.
#INT_VEC 0x10 myfunction
The above example causes the interrupt at offset 0x10 (Serial Port 1 of the
Z180) to invoke the function myfunction(). The function must be
declared with the interrupt keyword, as shown below.
interrupt myfunction() {
...
}
Refer to the Dynamic C manuals for further details on interrupt
functions.
