NOTE:
These two registers are protected from erase and program operations if
the EEDIVSECD is set to logic 1 in the EEDIVH (see
Timebase Divider
EEDIVHNVR.
Once EEDIVSECD in the EEDIVHNVR is programmed to 0 and after a
system reset, the EEDIV security feature is permanently enabled
because the EEDIVSECD bit in the EEDIVH is always loaded with a 0
thereafter. Once this security feature is armed, erase and program
operations are disabled for EEDIVHNVR and EEDIVLNVR.
Modifications to the EEDIVH and EEDIVL registers are also disabled.
Therefore, care should be taken before programming a value into the
EEDIVHNVR.
