NOTE:
Figure 5-8. EEPROM Divider Non-Volatile Register Low (EEDIVLNVR)
Address:
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 0
thereafter. Once this security feature is armed, erase and program mode
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.
The WAIT and STOP instructions can put the MCU in low power-
consumption standby modes.
The WAIT instruction does not affect the EEPROM. It is possible to start
the program or erase sequence on the EEPROM and put the MCU in
wait mode.
