Portenta H7 Core M4 start and reset with registers

Official Hardware Portenta Family Portenta H7

Good evening everyone,

I'm trying to develop a project with Portenta H7. The goal is to control the execution of the M4 core from M7. Specifically, after completing a configuration phase managed by M7, a value in the RCC->GCR register is modified to start M4. I was wondering if there is a similar command that allows resetting the M4 core by acting on the registers without stopping the execution of the M7 core.

void Board::M4Core_Start(Stream& SerialeCOM)
{
SerialeCOM.println("------------------------- START CORE M4  -------------------------------");
RCC->GCR |= (1 << 3);
SerialeCOM.println("------------------------- START CORE M4 COMPLETE -----------------------");
}

Thanks
