Note:

RESERVED address space must not be written under any circumstances. Failure to heed this warn-

ing may result in untoward operation and unexpected results. If it is necessary to write to registers

which contain both writable and reserved bits in the same register, the user should first read back

the reserved bits (RO or R/W), “OR” the desired settable bits with the value read, and then write

back the “ORed” value to the register.
