4.11.7.2. INT
Format: INT
This command indicates the beginning of an interrupt service
routine, and is used when the interrupt is conditional on the value
of an internal variable. The argument specifies the input
priority. is specified as a value from 0 to 7, where 0 is
the highest priority and 7 is the lowest. specifies on
which internal variable the interrupt is conditional. Any FSP
Amplifier variable can be used. and specify
the interrupt condition. As shown in Figure 54, any of the relational

4.11.7.3. INT_RETURN
Format: INT_RETURN
This command signals the end of an interrupt service routine.
specifies the program label to which the program must
proceed once the interrupt service routine has been completed.
Setting to –1 specifies that the program must simply
continue running from the point at which the interrupt occurred.
If an interrupt service routine of a lower priority interrupt is
executed after a higher priority interrupt service routine, the
program will continue from the position defined by the last
INT_RETURN command.
