All of the Control Register bits are nonvolatile (except for the
WEL bit), so they do not change when power is removed.
The values of the Register Block can be read at any time by
performing a random read (see Serial Interface) at the
specific byte address location. Only one byte is read by each
register read operation.
Bits in the registers can be modified by performing a single
byte write operation directly to the address of the register
and only one data byte can change for each register write
operation.
