Hardware Interrupts
The programmer can generate interrupts by using the software interrupt instruction (SWI), which
is supported in qFORTH by predefined macros named SWI0...SWI7. The software triggered
interrupt operates exactly like any hardware triggered interrupt. The SWI instruction takes the
top two elements from the expression stack and writes the corresponding bits via the I/O bus to
the interrupt pending register. Therefore, by using the SWI instruction, interrupts can be re-prior-
itized or lower priority processes scheduled for later execution.
In the microcontroller block, there are eleven hardware interrupt sources with seven different lev-
els. Each source can be masked individually by mask bits in the corresponding control registers.
