CC2340R5: reset function

Hi bijendra,

Writing 1 to the SCB:AIRCR:SYSRESETREQ bit causes the SYSRESETREQ signal to the outer system to be asserted to request a reset. The intention is to force a large system reset of all major components except for debug. The C_HALT bit in the DHCSR is cleared as a result of the system reset requested. The debugger does not lose contact with the device.  Thus it is a soft reset.

/**
  \brief   System Reset
  \details Initiates a system reset request to reset the MCU.
 */
__NO_RETURN __STATIC_INLINE void __NVIC_SystemReset(void)
{
  __DSB();                                                          /* Ensure all outstanding memory accesses included
                                                                       buffered write are completed before reset */
  SCB->AIRCR  = ((0x5FAUL << SCB_AIRCR_VECTKEY_Pos) |
                 SCB_AIRCR_SYSRESETREQ_Msk);
  __DSB();                                                          /* Ensure completion of memory access */

  for(;;)                                                           /* wait until reset */
  {
    __NOP();
  }
}
