+<sect1>Interrupts<p>
+
+The runtime for the Commodore 610 uses routines marked as <tt/.CONDES/ type 2
+for interrupt handlers. Such routines must be written as simple machine
+language subroutines and will be called automatically by the interrupt handler
+code when they are linked into a program. See the discussion of the
+<tt/.CONDES/ feature in the <htmlurl url="ca65.html" name="assembler manual">.
