This register contains a key that enables writes to the MSB of this register and the RSTCFG Register. The
key value is 0x5A69. A valid key will be stored as 0x000C, any other key value is invalid. When the
RSTCTRL or the RSTCFG is written, the key is invalidated. Every write must be set up with a valid key.
