QUESTION

I am using the Keil ULINK USB-JTAG/OCDS Adapter for debugging of an Infineon XC16x devices. In my program I have several peripherals running. Do this peripherals (such as timer or A/D converter) stop when I reach a breakpoint?

ANSWER

By default the peripherals do not stop when you reach a breakpoint. However the Infineon XC16x devices provide a OCDS Debug Peripheral Suspend Configuration OPSEN register. The OPSEN register is a protected register that must be either initialized before the EINIT instruction or by using a Security Level Command Register.

The START_V2.A66 CPU startup code version 5.06 or higher provides at setup for the OPSEN register.
