CAL, and RTCSC. All other registers are unlocked. Each key has an address associ-
ated with it in the internal memory map.
A write of 0x55CCAA33 to the associated key register changes the key to the open
state. A write of any other data to this location changes the key to the locked state.
The key registers are write-only. A read of the key register has undefined side effects
and may be interpreted as a write that locks the associated register.
