Note 1: While the ON bit (REFOxCON<15>) is ‘1’, writes to this register do not take effect until the DIVSWEN bit is
also set to ‘1’.
2: Do not write to this register when the ON bit (REFOxCON<15>) is not equal to the ACTIVE bit
(REFOxCON<8>).
3: Specified values in this register do not take effect if RODIV<14:0> (REFOxCON<30:16>) = 0.
