... Lock-up during ISP write – Program lock-up can be experienced when using Atmel FLIP software or a custom In system Pogramming tools to write in the internal EEPROM. This problem occurs with clock frequency > 12MHz in X2 mode or 24MHz in X1 mode. Neither the code Flash nor the EEPROM are corrupted by the lock-up. Although the EEPROM cannot be written by the bootloader ...
