MON166: SERIAL ISR OVERWRITTEN WHEN USING NMI ONLY OPTION

Information in this article applies to:

C166 Version 4.02

SYMPTOMS

I have written a project that includes a serial ISR. I have downloaded the monitor and selected the 'stop program execution with NMI only' option in µVision2.

When I download my program the monitor overwrites my serial ISR with its own, yet the monitor should only be using the NMI, not the serial interrupt.

CAUSE

This was a bug in the monitor in V4.02 that is corrected in the current release. You may download the latest updates from the Keil Website.

Make sure that you have configured your program to use only the NMI to halt program execution. To do so:

Open the project options dialog.
Select the Debug tab.
Select Settings for the Keil monitor (this button is located in the top right corner of the window).
In the monitor settings dialog, select NMI Only for Stop Program Execution.
