System reboot without NRST low

I'm using an STM32L152 with IAR embedded workbench.
This MCU has an external reset pin (NRST) which is bidirectional. The MCU outputs a low signal if its reset system detects a watchdog reset, software reset or low-power management reset. With other words: If I reboot the system using HAL_NVIC_SystemReset() the NRST pin is taken low.


Question: How can I reboot the system by software without signalling it at the NRST pin? Can I inhibit the NRST output pin or is there a way to call the reset vector to reboot?


Thanks for your support.
