EEPROM-1
5.6.5 EEPROM-1 Timebase Divider Non-Volatile Register
The 16-bit EEPROM-1 timebase divider non-volatile register consists of
two 8-bit registers: EE1DIVHNVR and EE1DIVLNVR. The contents of
these two registers are respectively loaded into the EEPROM-1
timebase divider registers, EE1DIVH and EE1DIVL, after a reset.
These two registers are erased and programmed in the same way as an
EEPROM-1 byte.

These two registers are protected from erase and program operations if
the EEDIVSECD is set to logic 1 in the EE1DIVH (see EEPROM-1
Timebase Divider Register) or programmed to a logic 1 in the
EE1DIVHNVR.
