Interrupt Handler Parameter
Your Interrupt Handler can be coded to receive a 32-bit parameter every time it is called.
The Parameter Type field is a pull down list used to identify what kind of parameter, if
any, your Interrupt Handler expects. If your Interrupt Handler has no need for a
parameter, set the
Parameter Type to (none).
If your Interrupt Handler expects a numeric parameter, set the
Parameter Type to Value
and enter the required unsigned, 32-bit hexadecimal numeric value into the Parameter
field.
If your Interrupt Handler parameter must be a pointer to a variable or function, set the
Parameter Type to Symbol and enter the name of the variable or function into the
Parameter field. The parameter must be a text string giving the name of a public symbol
(variable or function) defined in some module in your AMX application. The symbol's
32-bit value, as resolved by your linker, will be passed to your Interrupt Handler as its
parameter.
Prebuilt Clock ISPs
Clock drivers are provided with AMX for several common programmable interval timers.
In some cases, the AMX clock ISP can be prebuilt in your Target Configuration Module.
To select one of these clocks, click on the Prebuilt Clock ISPs... button. In the dialog box
which is presented, check the box for the particular clock driver which you wish to use.
If you do not wish to use a prebuilt clock ISP, leave all boxes unchecked.
