Soft reset is generated when the SYSRESETREQ bit of the application interrupt and reset control register (AIRCR) in the Arm® core is set. For more information, see Arm documentation.
When the application core performs a soft reset, the network core is held in reset, see Network Force-OFF. A soft reset in the network core will only cause the network core to reset.
A soft reset can also be generated using the RESET register in the associated CTRL-AP.
