Technical Data
NOTE:
Address:
In addition to the disabling of the program and erase operations on
memory locations $06F0–$06FF, the enabling of the protect option has
the following effects:
Once armed, the security option is permanently enabled. As a
consequence, all functions in the EENVR will remain in the state they
were in immediately before the security was enabled.
This read/write register controls programming/erasing of the array.

This read/write bit determines which clock will be used to drive the
internal charge pump for programming/erasing. Reset clears this bit.

1 = Bus clock drives charge pump.
0 = Internal RC oscillator drives charge pump.
Bulk and block erase modes are disabled.
Programming and erasing of the EENVR are disabled.
Unsecure locations ($0600–$06EF) can be erased using the
single byte erase function as normal.
Secured locations can be read as normal.
Writing to a secured location no longer qualifies as a valid
EEPROM write as detailed in
