Debugging hc12

[israel]

Hello,

I am new programmer in freescale. I am developing with codewarrior version 4.2.5.766. I inherited an existing project using the MC12S12DP256. this project uses the High wave for debugging together with the P&E for hc12.

Under the project setting I see the check box of using  External debugger and the hiwave.exe is directed. Few questions:

1. Can I use the IDE instead of the hiwave  to debug the hc12?

2. If the asnwer is Yes what do i need to do?

3. How can I use multi breakpoints to debug?

4. when I use the HiWave for debug and i go step by step I am jumping to one of the timming interrupt what can i do to overcome this?

No

3. How can I use multi breakpoints to debug?

The hardware supports 2 breakpoints, so that is how many you get in the debugger.

4. when I use the HiWave for debug and i go step by step I am jumping to one of the timming interrupt what can i do to overcome this?

Disable the timer while debugging. Click on the 'I' bit in the CCR from the debugger to disable interrupts momentarily.

"Click on the 'I' bit in the CCR from the debugger to disable interrupts momentarily"  .... can you give some more information about it

The debugger displays the condition-code register (CCR) as a string of condition-code flags, one letter per flag. The ones that are set will be black, and the ones that are cleared will be gray.

If you double-click on any of the condition-code flag bits, it will toggle. If interrupts are enabled, the "I" bit will be gray. You can mask all interrupts by double-clicking on the "I" bit to set it.

I need to do this on every breakpoint, since I always have interrupts enabled (except in an ISR), and the timers and SCI are always running. I wish it could be done automatically.
