STBCTLP - Stand-by control protection register
The 8-bit STBCTLP register protects the register STBCTL from inadvertent
write access.
After data has been written to the STBCTLP register, the first write access to
register STBCTL is valid. All subsequent write accesses are ignored. Thus, the
value of STBCTL can only be rewritten in a specified sequence, and illegal
write access is inhibited.
This register can only be written in 8-bit units.
