EEPROM-2
6.6.5 EEPROM-2 Timebase Divider Non-Volatile Register
The 16-bit EEPROM-2 timebase divider non-volatile register consists of
two 8-bit registers: EE2DIVHNVR and EE2DIVLNVR. The contents of
these two registers are respectively loaded into the EEPROM-2
timebase divider registers, EE2DIVH and EE2DIVL, after a reset.
These two registers are erased and programmed in the same way as an
EEPROM-2 byte.

These two registers are protected from erase and program operations if
the EEDIVSECD is set to logic 1 in the EE2DIVH (see EEPROM-2
Timebase Divider Register) or programmed to a logic 1 in the
EE2DIVHNVR.
