3.1 System Reset

CRU, RSWRST register and SWRST bit (RSWRST[1]) reset the software. This register is in the CRU at address 0x4400_0A00. A write of a logic 1 to this bit enables the software Reset. A subsequent read of this register triggers the system Reset sequence. The system unlock sequence must be done before the bit can be written. The system unlock register belongs to the CFG register CFG_SYSKEY at address 0x4400_00B0.

Run the following sequencer to unlock:
  1. Set CFG_SYSKEY=0x00000000 (Reset key)
  2. Set CFG_SYSKEY=0xAA996655
  3. Set CFG_SYSKEY=0x556699AA
