Chapter 3 2 Kbyte EEPROM Module (EETS2KV1)
3.5.3
In background debug mode (BDM), the EPROT register is writable. If the chip is unsecured then all
EEPROM commands listed in
mode, then the only possible command to execute is mass erase.
3.6
If a reset occurs while any EEPROM command is in progress, that command will be immediately aborted.
The state of the word being programmed or the sector / block being erased is not guaranteed.
3.7
The EEPROM module can generate an interrupt when all EEPROM commands are completed or the
address, data, and command buffers are empty.
