SIGINT, Interrupt

Hi All
While debugging the esp32 I get this message after setting a breakpoint

Program received signal
SIGINT, Interrupt.
0x400ea9da in esp_pm_impl_waiti () at C:\Users\yurr.platformio\packages\framework-espidf\components\esp32\pm_esp32.c:487
487 asm(“waiti 0”);

What does this mean?

Best regards
Yuri
