LPC1114: Stopping Timers on Breakpoints?

Working with an LPC1114 I found that while the CPU is halted on a breakpoint the timers continue to run. I´d prefer to stop all timers synchronously to the CPU, which would ease debugging quite a lot for me. Is this possible?

From a quick scan of the LPC11xx user manual....

Quote:

During a debugging session, the System Tick Timer is automatically stopped whenever the CPU is stopped. Other peripherals are not affected.

[I]Section 20.6 "Debug Notes" of UM10398, LPC111x/LPC11C1x User manual, Rev. 00.16 — 23 June 2010[/I]

Thus it sounds like only systick can be stopped, all the other timers will continue to run.

OK, thanks for making this clear.

BTW: The LPC13xx and LPC17xx series have in principle the same behaviour, the LPC17xx just stops additionally the Repetitive Interrupt Timer RIT.
