Hello,

You can check in the Cortex M0+ :

AIRCRa Application Interrupt and Reset Control Register in the ARMv6-M Architecture ReferenceManual.

Checking in the ARMv6-M RM :

In the AIRCR register, WO - SYSRESETREQ bit. : Writing 1 to this bit asserts a signal to request a reset by the external system.

This register is in address : 0xE000ED0C

So you should write the bit [2] SYSRESETREQ in that address to request a SW reset. Take care with the rest of the bits value, modify only that bit.

Regards,

Luis
