NOTE:
Once EEDIVSECD in the EE1DIVHNVR is programmed to 0 and after a
system reset, the EE1DIV security feature is permanently enabled
because the EEDIVSECD bit in the EE1DIVH is always loaded with 0
thereafter. Once this security feature is armed, erase and program mode
are disabled for EE1DIVHNVR and EE1DIVLNVR. Modifications to the
EE1DIVH and EE1DIVL registers are also disabled. Therefore, care
should be taken before programming a value into the EE1DIVHNVR.
The WAIT and STOP instructions can put the MCU in low power-
consumption standby modes.
The WAIT instruction does not affect the EEPROM-1. It is possible to
start the program or erase sequence on the EEPROM-1 and put the
MCU in wait mode.
The STOP instruction reduces the EEPROM-1 power consumption to a
minimum. The STOP instruction should not be executed while a
programming or erasing sequence is in progress.
If stop mode is entered while EELAT and EEPGM are set, the
programming sequence will be stopped and the programming voltage to
the EEPROM-1 array removed. The programming sequence will be
restarted after leaving stop mode; access to the EEPROM-1 is only
possible after the programming sequence has completed.
If stop mode is entered while EELAT and EEPGM is cleared, the
programming sequence will be terminated abruptly.
In either case, the data integrity of the EEPROM-1 is not guaranteed.
