C166: Do Peripherals Stop with ULINK2 Debugging?
Information in this article applies to:
I am using the Keil ULINK2 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?
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.
