LED Timing Issue in Timer Peripheral Example when Adjusting time_ms Value

[siltvm]

Hi,

I am currently developing a project using the nRF52810 as my controller, with SEGGER Embedded Studio (version 5.42a) and SDK version 17.0.2 as my development environment. During the development phase, I am testing the timer peripheral example project from the directory nRF5_SDK_17.0.2_d674dde\examples\peripheral\timer\pca10040\blank\ses. I flashed the code onto the nRF52832 PCA10040 development board, and the four LEDs on the board turn on and off based on the time_ms value.

The issue is that when I change the time_ms value from 1000 (1 second) to 300000 (5 minutes), the LED indications are incorrect. The LEDs turn on and off within 30 seconds instead of 5 minutes. However, when I change the time_ms value to up to 4 minutes, the LEDs behave as expected, with the correct 4-minute delay. What could be causing this issue?

Studio version 5.42a

SDK: nRF5 SDK 17.0.2
